Speed Time and Distance Example 4


Speed Time and Distance shortcut tricks are very important thing to know for your exams. Time takes a huge part in competitive exams. If you manage your time then you can do well in those exams. Most of us miss that part. We provide examples on Speed Time and Distance shortcut tricks here in this page below. These shortcut tricks cover all sorts of tricks on Speed Time and Distance. Visitors please read carefully all shortcut examples. These examples here will help you to better understand shortcut tricks on speed time and distance.

Before starting anything just do a math practice set. Then find out twenty math problems related to this topic and write those on a paper. Solve first ten math problems according to basic math formula. You also need to keep track of the time. Write down the time taken by you to solve those questions. Now go through our page for speed time and distance shortcut trick. After this do remaining ten questions and apply shortcut formula on those math problems. Again keep track of timing. You will surely see the improvement in your timing this time. But this is not all you want. You need more practice to improve your timing more.

You all know that math portion is very much important in competitive exams. That doesn’t mean that other sections are not so important. But if you need a good score in exam then you have to score good in maths. A good score comes with practice and practice. All you need to do is to do math problems correctly within time, and you can do this only by using shortcut tricks. Again it does not mean that you can’t do maths without using shortcut tricks. You may have that potential to do maths within time without using any shortcut tricks. But so many people can’t do this. So Speed Time and Distance shortcut tricks here for those people. Here in this page we try to put all types of shortcut tricks on Speed Time and Distance. But it possible we miss any. We appreciate if you share that with us. Your little help will help others.

Speed Time and Distance Example 4
This is the basic theory of Speed Time and Distance which is applied in question to obtain answers here is Speed Time and Distance Methods of example 4 in different form of examples. In maths exam papers there are two or three question are given from this chapter.

This type of problem are given in Quantitative Aptitude which is a very essential paper in banking exam. Under below  given some more example for your better practice.

 

 


Example #1
Rajib walks 170 meters every day. How many kilometers will he made in 4 weeks?

  1. 4.042 km
  2. 4.760 km
  3. 5.392 km
  4. 5.960 km

Show Answer Show How to Solve Open Rough Workspace

Answer: Option (B)
How to Solve
4 Weeks = 28 Days.
170 x 28 = 4760 meter.

Converting meter to km:
4760 / 1000
= 4.760 km.

Example #2
A bus covers the initial 46 km in 42 minutes and remaining 26 km covers in 38 minutes. Find the average speed of the bus.

  1. 54 km/hr
  2. 59 km/hr
  3. 63 km/hr
  4. 68 km/hr

Show Answer Show How to Solve Open Rough Workspace

Answer: Option (A)
How to Solve
Total distance covered by the bus:
46 + 26
= 72 km.

Total time taken to cover the distance:
42 + 38
= 80 min.

So, the average speed of the bus is:
72 x 60 / 80
= 54 km/hr.

Example #3
Ajay passes a car in 16 seconds. The same car passes a lamp post in 6 seconds. Find respective ratio between speed of Ajay and speed of the car.

  1. 7 : 2
  2. 2 : 7
  3. 3 : 8
  4. 8 : 3

Show Answer Show How to Solve Open Rough Workspace

Answer: Option (C)
How to Solve
1 / 16 : 1 / 6
= 3 : 8

So, the respective ratio between speed of Ajay and speed of the car is 3 : 8.

Example #4
A fast train covers a distance in 40 min. If it runs at a speed of 45 km/hr on an average. The speed at which the train must run to reduce the time of journey to 30 min will be?

  1. 50 km/hr
  2. 60 km/hr
  3. 70 km/hr
  4. 80 km/hr

Show Answer Show How to Solve Open Rough Workspace

Answer: Option (B)
How to Solve
The train covers the distance in 40 minutes.
OR, Time = 40 / 60
= 2 / 3 hr.

Given speed = 45 km/hr.
We know, Distance = Speed x Time.
So, Distance = 45 x (2 / 3)
= 30 km.

Now, the train covers the distance in 30 minutes.
OR, Time = 30 / 60
= 1 / 2 hr.

So, the new average speed will be:
Speed = Distance / Time
Speed = 30 x 2
= 60 km/hr.

Rough Workspace

Example #5
A man walking at the speed of 4 km/hr to cover a certain distance in 2 hr 45 min. Running at a speed of 16.5 km/hr the man will cover the same distance in what time?

  1. 18 min
  2. 25 min
  3. 30 min
  4. 40 min

Show Answer Show How to Solve Open Rough Workspace

Answer: Option (D)
How to Solve
We know that,
Distance = Speed x Time
So, Time = 2 hr 45 min
= 2 x 60 min + 45 min
= 165 min OR 165 / 60
= 11 / 4 hr.

Distance = 4 x 11 / 4
= 11 km.

So, the time required to cover the distance at the speed of 16.5 km/hr is:
Time = Distance / Speed
Time = 11 / 16.5
Time = 40 min.

Rough Workspace

Example #6
A train traveling at a speed of 90 km/hr overtakes a bike traveling at the speed of 54 km/hr in 30 seconds. What is the length of the train in meters?

  1. 300 Meters
  2. 320 Meters
  3. 360 Meters
  4. 395 Meters

Show Answer Show How to Solve Open Rough Workspace

Answer: Option (A)
How to Solve
The distance travailed by the train overtaking the bike is the same as the length of the train.
Also remember that both the objects are moving in same direction.

So, ( 90 – 54 )
= 36 km/hr.

Now, converting km/hr to min/sec:
36 x (5 / 18)
= 10 min/sec.

So, distance travailed in 30 seconds:
10 x 30
= 300 meters.
