Given information
As per the given question
The train accelerates at 
until it reaches 
. Then, it moves with uniform velocity then retards at 
until it comes to rest in the stop. The train stops for 
at each station.
Step-by-step explanation
Step 1.
To Determine the time taken by a train to make a 
trip in two situations we will use equations of motion,
Equations of motion:
Where, 
is the final velocity, 
is the initial velocity, 
is the acceleration, 
is the displacement and 
is the time.
Convert the velocity from 
to 
The maximum velocity is
