Question

A train 1.2 kilometre in length takes 108 seconds to overtake a telephone post. find the speed of the train

Answer 1

Answer:

when a train overtakes a telephone post it means that it is covering the distance of is own length.

first we will convert 1.2 km into merer because given time is in seconds(108sec)

1.2km =1200m

now, speed =distance÷time

speed=1200÷108

speed=11.11m/s
