A goods train runs at the speed of 72 kmph and crosses a 250 m long platform in 26 seconds. What is the length of the goods train?
[A].
[B].
[C].
[D].
Answer: Option D
Explanation:
| Speed = | 72 x | 5 | m/sec | = 20 m/sec. | |
| 18 |
Time = 26 sec.
Let the length of the train be x metres.
| Then, | x + 250 | = 20 |
| 26 |
x + 250 = 520
x = 270.
