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 |

There for 9seconds convert into hours.
60km convert into meters.
9/3600 * 60000 = 150.
60km convert into meters.
9/3600 * 60000 = 150.

@All.
Here, Speed of the train = 60×(5/18) = 50/3.
Here, Speed of the train = 60×(5/18) = 50/3.

For km;
a/hr = (a*5%18).
And for m;
a/hr = (a * 18%5).
a/hr = (a*5%18).
And for m;
a/hr = (a * 18%5).

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)...
