A car travels 20 km east and then 10 km west in 2 hours. What is its average speed?

A person walks 6 km due east and then 8 km due north. What is the magnitude of their displacement from the starting point?

A particle moves for 20 seconds with velocity 3 m/s and then velocity 4 m/s for another 20 seconds and finally moves with velocity 5 m/s for next 20 seconds. What is the average velocity of the particle in m/s is

A car travels for a time $t$ with speed $v$ and then for an equal time $t$ with speed $3v$. What is the average speed of the car?

The velocity of particle is $v = {v_0} + {\rm{g}}t + f{t^2}.$. If its position is x=0 at t=0, then its displacement after unit time (t=1) is

The co-ordinates of a moving particle at time t are given by $x = c{t^2}\,\,and\,\,y = b{t^2}.$ The instantaneous speed of the particle is

A particle is moving with a constant speed v in a circle. What is the magnitude of average after half rotation?

An object accelerates from rest to a velocity $27.5\;{\rm{m}}{{\rm{s}}^{ - 1}}$ in 10 s, then the distance covered after next 10 s is

A cyclist travels half the distance with speed $v$ and the remaining distance with speed $2v$. What is her average speed?

A car travels 20 km east and then 10 km west in 2 hours. What is its average speed?

A particle moves 10 meters east and then 5 meters west. What is its total distance traveled?
