Question:

A train 400 m long travels at a speed of 36 kmph. Find the time it would take to cross a platform 300 m long.

Options:

30 sec

60 sec

35 sec

70 sec

Correct Answer:

70 sec

Explanation:

Speed in m/s = 36 x \(\frac{5 }{18 }\) = 10m/s

time = \(\frac{distance }{speed}\)

time = \(\frac{\text{400 + 300} }{10}\)

time = \(\frac{700}{10}\)

time = 70 seconds
