Question:

A 100 m long train is running at the speed of 30 Km/hr. Find the time taken by it to pass a man standing near the railway line?

Options:

10 Sec

12 Sec

16 Sec

20 Sec

Correct Answer:

12 Sec

Explanation:

Speed = \(\frac{Distance }{Time }\)

30 x \(\frac{5 }{18 }\) = \(\frac{100 }{Time }\)

\(\frac{25 }{3}\) = \(\frac{100 }{Time }\)

Time = \(\frac{300 }{25 }\) = 12 seconds
