Question

a train 315 M long is running at 54 km per hour how much time will take to cross a pole

Answer 1

Given :

A train 315 M long is running at 54 km per hour h

To Find :

how much time will take to cross a pole

Solution:

Length of train = 315 m

1000 m = 1 km

$1 m = \frac{1}{1000} km$

315 m = $\frac{1}{1000} \times 315 =0.315 km$

Length of train = 0.315 km

Speed = 54 km/hr

Time = $\frac{distance}{Speed}=\frac{0.315}{54}=0.0058 hours$

Hence it will take 0.0058 hours to cross a pole.
