Question

A student goes to school from home, which is
2 km away when he travel by road and net
displacement is 2 km. If he travelled by car
on road with constant speed 20 km/h, then
average speed and average velocity of car are
respectively
20 kmph, 20 kmph
20 kmph, 10v2 kmph
20 kmph, 2012 kmph
102 kmph, 20 kmph​

Answer 1

Answer:

20 kmph, 20kmph

Explanation:

Distance = 2 km

Displacement = 2km

Distance = Displacement means Speed= Velocity

Constant speed = 20 kmph

Constant speed = average speed

hence, average speed = average velocity = 20 kmph
