Question
A child is standing on the platform of a station, watching the trains.A train travelling at 30 m/s takes 3 s to pass the child. What is the length of the train?
Solution
The length of the train can be calculated using the formula:
Speed = Distance / Time
We know the speed of the train (30 m/s) and the time it takes to pass the child (3 seconds). We can rearrange the formula to solve for distance, which in this case is the length of the train:
Distance = Speed * Time
Substituting the given values:
Distance = 30 m/s * 3 s = 90 m
So, the length of the train is 90 meters.
