A train running at the speed of 60 km/hr crosses a pole in 9 seconds. What is the length of the train ?


A) 120 metres

B) 180 metres

C) 324 metres

D) Cannot be determined

E) None of these

Answer:

Option E

Explanation:

Speed $=\left(60\times\frac{5}{18}\right)$ m/sec $=\left(\frac{50}{3}\right)$ m/sec.

Length of the train = (Speed $\times$ Time) $=\left(\frac{50}{3}\times 9\right)$ m = 150 m.
