Answer 2

Answer:

Length of the train is equal to the distance covered by train to cross the pole. So, we will find the distance travelled by the train in 12 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=45* 5/18 = 12.5 m/s

Time = 12 seconds

Distance = 12.5 * 12= 150meters

ans is the length of train is 150 m
