Let length of platform be a
Then
Distance = Speed × Time
(250 m + a) = [48 × 5/18 m/s] × 39 s
(250 m + a) = 520 m
a = 520 m - 250 m
a = 270 m
Length of the platform is 270 m
Then
Distance = Speed × Time
(250 m + a) = [48 × 5/18 m/s] × 39 s
(250 m + a) = 520 m
a = 520 m - 250 m
a = 270 m
Length of the platform is 270 m
