Problem on finding length of Train or Platform

The problem on trains are important chapter for easily get the marks in competitive exam papers. you just remember the way of train cross the object and speed, time and distance. There are train based problem based on two object, First is Train and second object is that which is crossed by the train.

Example #1 – Problem on finding length of train or platform

A 120 meter long train passes a bridge in 18 sec, moving with a speed of 108 km/hr. What would be the length of the bridge?

340 Meters

370 Meters

400 Meters

420 Meters

Show AnswerShow How to SolveOpen Rough Workspace

Answer: Option (D)

How to Solve Speed = 108 x 5 / 18 Speed = 30 m/sec.

Let, the length of the bridge is X. Speed = Distance / Time 30 = 120 + X / 18 120 + X = 540 X = 540 – 120 X = 420

Example #2 – Problem on finding length of train or platform

A mail train of 240 meters long, traveling at a uniform speed and crosses a bridge in 80 second and a boy standing on the bridge in 40 seconds. What is the length of bridge?

222 Meters

240 Meters

268 Meters

292 Meters

Show AnswerShow How to SolveOpen Rough Workspace

Answer: Option (B)

How to Solve 240 / 40 = 6 m/sec. 6 = X + 240 / 80 X = 480 – 240 X = 240 meters.

Example #3 – Problem on finding length of train or platform

A metro rail is running at the speed of 90 km/hr. If crosses a platform whose length is twice that of the train in 36 seconds. What is the length of platform in meter?

400 Meter

500 Meter

600 Meter

700 Meter

Show AnswerShow How to SolveOpen Rough Workspace

Answer: Option (C)

How to Solve Speed = 90 x 5 / 18 Speed = 25 m/sec.

25 = X + 2X / 36 X = 300 meter.

So, length of platform is, 300 x 2 = 600 meter.

Example #4 – Problem on finding length of train or platform

An express train passes a tunnel in 21 seconds. The length of the train is 130 meter and moving at the speed of 90 km/hr. What is the length of the tunnel?

378 Meters

395 Meters

423 Meters

461 Meters

Show AnswerShow How to SolveOpen Rough Workspace

Answer: Option (B)

How to Solve Let, the length be the tunnel is X meters. Now, converting km/hr to m/sec, 90 x 5 / 18 = 25 m/sec.

25 = 130 + X / 21 130 + X = 25 x 21 X = 525 – 130 X = 395.

So, the length of the tunnel is 395 meters.

Example #5 – Problem on finding length of train or platform

An express train is running at the speed of 90 km/hr. It crosses a bridge, whose length is twice that of the train, in 36 seconds. What is the length of bridge in meter?

460 Meter

495 Meter

540 Meter

600 Meter

Show AnswerShow How to SolveOpen Rough Workspace

Answer: Option (D)

How to Solve Converting the speed 90 km/hr into m/sec, 90 x 5 / 18 = 25 m/sec.

Let, the length of the train is X. So, the length of the bridge is 2x.

Now, 25 = X + 2X / 36 X = 300 meter.

So, the length of the platform is, 300 x 2 = 600 meter.

Example #6

An express train passes by a boy standing on the platform in 9 seconds and passes by the platform completely in 27 seconds. If the length of the platform is 350 meters, then what is the length of the train?

175 Meters

199 Meters

210 Meters

221 Meters

Show AnswerShow How to SolveShow Shortcut TricksOpen Rough Workspace

Answer: Option (A)

How to Solve Let, the length of the train be X meters. Then, speed of the train = X / 9 m/sec.

And, also the speed of the train is, = X + 350 / 27 m/sec.

Both the speed should be equal, i e, X / 9 = X + 350 / 27. 27X – 9X = 9 x 350 X = 9 x 350 / 18 X = 175 meters.

Shortcut Tricks Length of train = Length of platform / Difference in time x Time taken to cross the man. Or, Length of train = 350 x 9 / 18 Or, Length of train = 175 meters.

Example #7

A local train crosses a bridge in 30 seconds. If the length of the local train is 300 meter, then what is the length of the bridge?

300 Meters

378 Meters

401 Meters

Can’t Determined

Show AnswerShow How to SolveOpen Rough Workspace

Answer: Option (D)

How to Solve To find length of the bridge, we need the speed of local train. Which has not given here. So, we can’t determined the length of the bridge.

Example #8

A bike travel a distance in 13 hours. The 1st half of it at 24 km/hr and the 2nd half at 28 km/hr. Find the distance of his total journey.

281 Kilometers

305 Kilometers

336 Kilometers

353 Kilometers

Show AnswerShow How to SolveOpen Rough Workspace

Answer: Option (C)

How to Solve Let, the total distance is X. ( X / 2 / 24 ) + ( X / 2 / 24) = X / 48 + X / 56 7X + 6X / 336 = 13 13X / 336 = 13 X = 4368 / 13 X = 336 Kilometers.

দুটি ট্রেন যথাক্রমে 12km/h ও 6km/h গতিবেগে আসে। যদি প্রথম ট্রেনটি দ্বিতীয় ট্রেনের একজন যাত্রীকে 10 secconds এ অতিক্রম করে , তবে প্রথম ট্রেনের length (দৈর্ঘ্র্য) কত?

A train passes a station platform in 30 sec and a man standing on a platform in 20 sec if the speed of train is 54km/hr what is the length of the platform A.120 B.100 C.200 D.256 I need a answe

Let’s assume the length of the train is X. So, in 2 minutes the train covers 1.5km + length of the train. therefore, 2 = 1.5 + X

And, in 60 minutes the train runs 60km. So, in 2 minutes the train covers 2km.

Now, we see that, in 2 minutes the train runs 2 kilometers and in 2 minutes it cross 1.5 + X kilometers. By evaluating these two values, we can say that, 2km = 1.5km + X or, X = 2km – 1.5km or, X = .5km / 500 meters

Thank you sir….Easy to understand…But i need some complicated problems..

দুটি ট্রেন যথাক্রমে 12km/h ও 6km/h গতিবেগে আসে। যদি প্রথম ট্রেনটি দ্বিতীয় ট্রেনের একজন যাত্রীকে 10 secconds এ অতিক্রম করে , তবে প্রথম ট্রেনের length (দৈর্ঘ্র্য) কত?

Hello dear, the example no. 2 is n’t correct i think, because 240 will substract from 480 and result will be 240.

thankyou sir….plz provide more questions…

I need a answe

if suppose train run mumbai to pune per hour 60km speed and its cross bor ghat 1.5 km in 2 min then what is the length of the train

Let’s assume the length of the train is X.

So, in 2 minutes the train covers 1.5km + length of the train.

therefore, 2 = 1.5 + X

And, in 60 minutes the train runs 60km.

So, in 2 minutes the train covers 2km.

Now, we see that, in 2 minutes the train runs 2 kilometers and in 2 minutes it cross 1.5 + X kilometers.

By evaluating these two values, we can say that,

2km = 1.5km + X

or, X = 2km – 1.5km

or, X = .5km / 500 meters

So, the length of the train is 500 meters.
