Answer:
54 m/s
Explanation:
Formula: Distance = Speed * Time
Distance = 100 + 125 = 225 m
Time = 15 s
Speed = 225/15 m/s
= 54 m/s

Given: Length of a train = 100m
Length of a platform = 125 m
Time = 15 seconds
To find: Speed of the train
Solution:
Distance covered by the train will be equal to the length of the train and the platform the train crosses.
Therefore, the distance will be the sum of both the length = ( 100 + 125 )m = 225m
Time is taken to cross the platform = 15 seconds.
The speed of the train will be the distance covered by the train per unit time.
Speed = Distance covered / Time taken
= 225/15 = 15 m/s
Therefore, the speed of the train will be 15 m/s.
- Speed - Speed is the distance covered by the body per unit of time. It is a scalar quantity.
