A goods train runs at a speed of 72 km/h and crosses a 250 m long platform in 26 seconds. What is the length of the goods train?
A
230 m
B
240 m
C
260 m
D
270 m
Correct Option:
D
Explanation
Convert the speed: 72 km/h = 72 × 5/18 = 20 m/s. In 26 seconds, the train travels 20 × 26 = 520 m. To completely cross a 250 m platform, it covers its own length plus 250 m. Therefore, L + 250 = 520, so L = 270 m.
