Question

A man walk at the speed of 7/3 km /hr for 2 hours and then at the speed of 3/2 km /hr for the next 2 hour find the distance travelled by the man in 4 hours

Answer 1

First of all convert speed into meter per second by multiplying 7/3 & 3/2 with 1000 and then divided both 3600 because

1km=1000m

1 hour =3600s.

Now apply formula

s= v× t on both values

At the end Add S1 distance and S2 distance.

It will be distance travelled by the man in 4 hours.

Any confusion then asked me again
