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
