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?
Answer & explanation
Correct answer: option 2
Speed = \(\frac{Distance }{Time }\)
30 x \(\frac{5 }{18 }\) = \(\frac{100 }{Time }\)
\(\frac{25 }{3}\) = \(\frac{100 }{Time }\)
Time = \(\frac{300 }{25 }\) = 12 seconds
