Answer:
length of train + length of plarform = speed *time
a/q length is T = 100
Length of P = 60
and speed = 20m/s
100+60= 20* T
T= 8sec

Step-by-step explanation:
20m/s =20min in 1 second
Distance travelled = 100m + 60m= 160m,20m
Time take to travel = x second, 1second
Let the time taken to cover the distance be x second.
It varies directly.
x × 20= 160× 1
x=160×1/20
x= 8
Answer = 8 seconds
