Question

A car travels from station A to B at 30kmph and then back to A at 7o kmph. Find the average speed and average velocity of the car.
1) 35kmph,35kmph 2)42kmph,zero 3)42kmph,42kmph 4)35kmph, zero.

Answer 1

Answer:

brainliest

Explanation:

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
