Question

a car travels from A to B at a speed of 20km/h and returns at A speed of 40km/h . Calculate the average speed and average velocity of the car.​

Answer 1

Answer:

24 km/hr

Let distance from A to B be x

Time for travel from A to B= x/20

Time for travel from B to A= x/30

Hence,speed for total distance 2x is: 30x+20x2x=5x2x×60=24 km\hr
