Question 66

A train, 150 m long is running at 90 km/h. How long (in seconds) will it take to clear a platform that is 300 m long?

Solution

Given,

Length of the train (L) = 150 m

Length of the platform (l) = 300 m

Speed of the train (s) = 90 km/h = $$\text{90}\times\frac{5}{18}$$ m/s = $$\text{25}$$ m/s

Time taken by the train to cross the platform = $$\frac{L+l}{s}=\frac{150+300}{25}=\frac{450}{25}= \text{18}$$ seconds

Hence, the correct answer is Option D
