A car can be stopped within a distance of s when its speed is v. What is the minimum distance within which the car can be stopped during the same time when its speed is nv ?

A driver having a definite reaction time is capable of stopping his car over a distance of 30 m on seeing a red traffic signal, when the speed of the car is 72 km/hr andover a distance of 10 m when the speed is 36 km/hr. Find the distance over which he can stop the car if it were running at a speed of 54 km/hr. Assume that his reaction time and the deceleration of the car remains same in all the three cases.

If x is the distance at which a car can be stopped when initially it was moving with speed u, then on making the speed of the car Nu, the distance at which the car can be stopped is

A car takes 2 hours more to cover a distance of 480km when its speed is reduced by 8kmph . Find its usual speed
