Question

A 60 m long train moving on a straight level track passes a pole in 5 s, the speed of the train is

• A. 12 m/s
• B. 13 m/s
• C. 15 m/s
• D. 25 m/s

Answer 1

The correct option is A 12 m/s

Given, length of the train = $60m$ and time taken to cross the pole = $5s$
Speed of the train
$=\frac{\text{Length of the train}}{\text{Time taken to cross the pole}}$
$=\frac{60}{5}$$=12m{s}^{-1}$
