**Note: If direction is given in the opposite direction then we add both speeds.**

Example #1

180 meter and 120 meter mail train are running parallel in the opposite direction at the speed of 67 km/hr and 77 km/hr respectively. Find how long they take to cross each other?

- 13 / 2 Seconds
- 15 / 2 Seconds
- 17 / 3 Seconds
- 19 / 3 Seconds

**Answer:**Option (B)

**How to Solve**

Speed = Distance / Time

( 67 + 77 ) x 5 / 18 = 180 + 120 / Time

Time = 15 / 2 seconds.

Example #2

170 meter and 130 meter long two super fast train are running in opposite direction at the speed of 52 km/hr and 56 km/hr respectively. In what time would be they cross each other?

- 10 Seconds
- 12 Seconds
- 14 Seconds
- 16 Seconds

Show Answer Show How to Solve Open Rough Workspace

**Answer:**Option (A)

**How to Solve**

Convert speed km/hr to m/sec.

( 52 + 56 ) x 5 / 18

= 108 x 5 / 18

= 30 m/sec.

Time = Distance / Speed

= 170 + 130 / 30

= 300 / 30

= 10 sec.

So, they cross each other after 10 seconds.

Example #3

A passenger train of 330 meter long, running at a speed of 60 km/hr. In what time will it pass a man who is running at a speed of 6 km/hr in the opposite direction.

- 15 Seconds
- 18 Seconds
- 22 Seconds
- 25 Seconds

Show Answer Show How to Solve Open Rough Workspace

**Answer:**Option (B)

**How to Solve**

If direction is given in the opposite direction then we add both the speed.

( 60 + 6 )

= 66 km/hr.

Now, convert it into m/sec.

66 x 5 / 18

= 55 / 3 m/sec.

The total distance covered by the train at 55 / 3 m/sec speed is 330 meter.

So, the required time is,

330 x 3 / 55

= 18 sec.

Example #4

Two super fast train 180 meters and 180 meters in length respectively are running in the opposite directions. One at the speed of 58 km/hr and the other at the speed of 50 km/hr. What time will they take to completely clear each other from the moment they meet?

- 10 Seconds
- 12 Seconds
- 15 Seconds
- 18 Seconds

Show Answer Show How to Solve Open Rough Workspace

**Answer:**Option (B)

**How to Solve**

Two fast trains are running is opposite direction and their relative speed is,

58 + 50

= 108 km/hr.

So, the two trains are each other meet at 108 km/hr.

108 x 5 / 18

= 30 m/sec.

So, the required time is,

Total length / Relative speed

= 180 + 180 / 30

= 12 sec.

If two trains moving in opposite directions at the speed of 80 kmph and X kmph reach their destinations in 72 min and 32 min after they pass each other find X

I am not very sure, but since speed is inveresely proportional to itme so

s1/s2 = t2/t1

whhich gives

80/x = 32/72

x= 180kmph
