If a racing car covers 1000 km in 4 hours then find its speed.
Given, distance covered by racing car = 1000 km
Time took to cover 1000 km = 4 h
∵ Speed = distancetime
⇒ speed of car = 10004
= 250 km/h
If a racing car covers 500 km in 4 hours then find its speed.
If car A is at 40 km/h and car B is at 10 km/h in the opposite direction, what is the velocity of the car A relative to the car B?
