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.

How it is possible? train length = x metres then distance =2x metres.

Same Direction (46-36) = 10,
length= speed * time.
(10*5/18)*36 = 50.
length= speed * time.
(10*5/18)*36 = 50.

= [10*5/18]*36.
= 100.
= √100 = 50.
= 50 is the answer.
= 100.
= √100 = 50.
= 50 is the answer.
