A train moving at speed of 180 km/hr crosses a pole in 7 seconds. Find the length of the train.

OPtion

1) 250
2) 300
3) 350
4) 175
5) 700
6) 150
7) 125
8) 375
9) 325
10) None of these

Solution

Length of the train is equal to the distance covered by train to cross the pole. So, we will find the distance traveled by the train in 7 seconds by applying the following formula:

Distance= Speed x Time

Speed is given in Km/hr so we will convert it into m/s as answers are given in meters.

Speed=180*5/18 = 50 m/s
Time = 7 seconds

Distance = 50 * 7= 350 meters
