Question

A car travels half of the distance with constant velocity 40 km/h and another half with a constant velocity of
60 kmh along a straight line. The average velocity of the car is
(2) 48 km/h
(1) 24 km/h
(4) 40 km/h
(3) 60 km/h​

Answer 1

Answer:

I will tell you a short cut.

the average velocity will be the geometric mean of the two velocity data given i.e

average velocity=2v1v2/(v1+v2)=48 km/hr
