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. |

Distance = speed * time.
= 60 * 5/18 * 9 = 150m.
= 60 * 5/18 * 9 = 150m.

Distance = s * t = 60 * 5/18 * 9 = 150m.

Speed = 60 km/hr = 16.67 m/s.
Distance = Speed × Time = 16.67 × 9 = 150 m.
Distance = Speed × Time = 16.67 × 9 = 150 m.

@All.
Clear and well-explained!
The key is converting km/hr to m/s using the multiplication factor of 5/18.
This comes from the conversion: 1 km/hr = (1000 m)/(3600 s) = 5/18 m/s.
Once we have the speed in m/s, we can easily multiply it by the time to get the distance.
