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 |

A km/hr = [a×5÷18]m/s.
60 = [9×5÷18].
5÷2×60 = 150 meter.
60 = [9×5÷18].
5÷2×60 = 150 meter.

60 * 5/18 = 50/3,
Length = speed * time.
l = 50/3 * 9sec= 150 meters.
Length = speed * time.
l = 50/3 * 9sec= 150 meters.

1 km = 1000.
1 hr = 3600 s.
Why it is changed into 10/36 and 5/18?
1 hr = 3600 s.
Why it is changed into 10/36 and 5/18?

If they asking to find the length of the pole, then how to solve it?

60 km/h.
1 km/minutes.
1000/60 = 16.6666/sec
16.6666*9 = 150meter.
1 km/minutes.
1000/60 = 16.6666/sec
16.6666*9 = 150meter.

1 km = 1000 meters.
1 hr = 3600 seconds.
1 km/hr = 1000/3600 m/s.
1 hr = 3600 seconds.
1 km/hr = 1000/3600 m/s.

Why is the length of train calculated with the formula speed*time?

@Latha, Please explain the solution.
(sqrt(3N))^3/2 = 90.
N = 10.
(sqrt(3N))^3/2 = 90.
N = 10.
