Ans.-The speed of the man crossing the bridge at the rate of 4mins per m is q25m per min.
Given : A running man crosses a bridge of length 500 meters in 4 minutes.
To find : We can simply solve this mathematical problem by using the following mathematical process.
Solution :
We can simply solve this mathematical problem by using the following mathematical process.
The given statement indirectly says that, the man covers a distance of 500 meters in 4 minutes.
Now,
He can cover in 4 minutes = 500 m
He can cover in 1 minute = 500/4 m
He can cover in 60 minutes = (500×60)/4 = 7500m
He can cover in 1 hour = 7.5 km
(As, 60 minutes = 1 hour ; 1000m = 1 km)
Hence, his speed will be 7.5 km/h
