Question

A car travels from station A to B at 30kmph and then back to A at 70 kmph.
Find the average speed and average velocity of the car.​

Answer 1

Answer:

Explanation:Average Velocity = 0;Average Speed = 35kmph

Explanation:

Let distance between A to B is x

Average Velocity = 0 because displacement = 0

average speed is total distance/total time

THEN

Total distance = 2x and Total time=distance / speed

Lets first find average speed of speeds during return trip to A that is

after simplification 5x/210.Now lets go to main equation.

after simplification answer is 35kmph

Answer 2

Answer:

V.av= 42km/h.
