A car moves from A to B with a speed of 30 kmph and from B to A with a speed of 20 kmph. What is the average speed of the car ?

A

25 kmph

B

24 kmph

C

50 kmph

D

10 kmph

Text Solution

Verified by Experts

The correct Answer is:
b
`v_(av)=(2v_1 v_2)/(v_1 +v_2)=(2xx30xx20)/(30+20)=(1200)/(50)=24 km//hr`
