Question

A train 100m long with a velocity of 60km/hr . Find the time taken to cross the bridge in 1 km/hr

Answer 1

60km/h * 5/18 (first convert it in m/s)

=16.66m/s

now

total distance is 100+1km= 1100m

then, time taken to cross  the bridge will be;

s=d/t

16.66=1100/t

t=1100/16.66 answer

hope this will help to you
