1.
A train running at the speed of 60 km/hr crosses a pole in 9 seconds. What is the length of the train?
Answer: Option
Explanation:
| Speed = |  |
60 x | 5 |  m/sec |
= | |
50 | m/sec. |
| 18 | 3 |
Length of the train = (Speed x Time).
 Length of the train = |
|
50 | x 9 | m = 150 m. |
| 3 |

Let length of the train be 'x' metres...
Speed of the train = 60km/hr(given)
Time = 9seconds(given)
refer the formulas for train problems...
As the time is given in seconds and answers are given in metre(train length) we are in need to convert from km/hr to m/s
km/hr = 1000m/(60min*60sec) = 5/18 m/s
Length of the train(distance covered a post)= speed * time
= (60*(5/18))*9
= (50/3)*9
= 150 m
For the train related formulas,check the READ MORE in Left corner(Important formulas)...

Why se converting m/sec into km/sec?

v=d/t means
velocity=distance/time
velocity=distance/time

It's useful to science students,and every student know the how to change the units.
so thankyou very much sir.
