Question

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. 150 metres

Answer 1

The correct option is

D

150 metres

As train crosses the pole, the train has to cover its own length.so the entire length of train takes 9 sec to cross the pole, we can use,

$distance=velocity\times time$

Given, $v=60km/h=\frac{60\times 1000}{3600}m/s$

and $t=9s$

Length of the pole$=vt=\frac{60\times 1000}{3600}\times 9=150m$
