A train moves at the speed of 80 km/h and crosses a platform in 0.75 minutes. If the length of the train is equal to the length of the platform, then what is the length of the platform?
Answer & explanation
Correct answer: option 4
Given :-
Speed of train = 80 km/h
80 km/h = 80 × \(\frac{5}{18}\) m/sec
Time = 0.75 minutes = 45 seconds
Distance = Speed × Time
= 80 × \(\frac{5}{18}\) × 45 = 1000 m
According to question ,
Length of platform = Length of Train
Let length of train = D
So , 2D = 1000 m
D = 500 m
So , Length of platform = 500 m
