Question 52
A railway train 100 metres long is running at the speed of 30 km/hr. In what time does it pass a man standing near a line
Solution
Speed of train = 30 km/hr = $$(30\times\frac{5}{18})$$ m/s = $$\frac{25}{3}$$ m/s
Length of train = 100 m
Time taken = distance/time
= $$100\div\frac{25}{3}$$
= $$100\times\frac{3}{25}$$
= $$4\times3=12$$ seconds
=> Ans - (C)
