Question

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

Answer 1

Speed of the train$=60km/h=60\times \frac{5}{18}m/s$

Time taken to cross the pole$=9sec$

Length of the train$=speed\times time$ $=60\times \frac{5}{18}\times 9=150m$

Hence, $150m$ is the length of the train.
