GIVEN:-
A train of 450m long is running at a uniform speed 45km/h
TO FIND :-
Time taken to cross 550m lenght
SOLUTION :-
45kmph = 45 × 18 5 = 12.5m/s
total length covered by train = 450m + 550m = 1000m
velocity = Dispacement / time
t = s / v
t =1000 / (12.5m/s)
t = 80s
time is taken to cross the bridge is 80 seconds
