A train 125 m long passes a man, running at 5 km/hr in the same direction in which the train is going, in 10 seconds. The speed of the train is:
Answer: Option
Explanation:
| Speed of the train relative to man = |  |
125 |  m/sec |
| 10 |
| = | |
25 | m/sec. |
| 2 |
| = | |
25 | x | 18 | km/hr |
| 2 | 5 |
= 45 km/hr.
Let the speed of the train be x km/hr. Then, relative speed = (x - 5) km/hr.
x - 5 = 45 
x = 50 km/hr.

125/10 = 12.5,
12.5 * 3.6 = 45,
45 + 5 = 50.
12.5 * 3.6 = 45,
45 + 5 = 50.

x - 5 = 45
x= 45+5
x = 50 km/hr.
x= 45+5
x = 50 km/hr.
