Question

what will be the time taken by a train of length 375m traveling at a uniform speed of 50km/h to cross a 75m bridge completey​

Answer 1

Step-by-step explanation:

s=50km/h

d=75m = converting m into km= 75/1000=0.075km

=t=d/t

t= 0.075km/50km/h=0.0015hour

or

0.0015/1= 15/1000

=15/1000hours ans.
