Numerical Problems:
1. A railway train 50 m lng passes over a bridge 250 m long at a uniform rate of 10 m s-1. How long will it take to pass over the bridge?

Open in App

Solution

length of train = l = 50 m
length of bridge = b =250 m
Total distance travelled = 300 m

Speed = 10 ms^-1
Time taken = distance/speed
= 300/10
= 30 sec
