Two trains of equal length are running on parallel lines in the same direction at 46 km/hr and 36 km/hr. The faster train passes the slower train in 36 seconds. The length of each train is:
Answer: Option
Explanation:
Let the length of each train be x metres.
Then, distance covered = 2x metres.
Relative speed = (46 - 36) km/hr
| = |  |
10 x | 5 |  m/sec |
| 18 |
| = | |
25 | m/sec |
| 9 |
 |
2x | = | 25 |
| 36 | 9 |
2x = 100
x = 50.

By using the formula, if we solve the problem in SI unit we get 49.86 as answer.

If length of each train is supposed as x. Then how could distance cover is 2x?

It should be mentioned that the faster train started behind the slower train.

Why should we take relative speed is (46-36) in this case they are parallel?
