Two cars `A` and `B` are running with same speed `v`. A along east and `B` towards north. Car `A` is at origin `O` and `B` is at distance `d` as shown. After how much time, the distance between cars is minimum and what is the minimum distance?

Two cars A and B travel from the same point and in the same direction. A is travelling at a speed of 30 k(m) / hour and B at a speed of 40 (km) / hour . After 4 hours, what is the distance between the cars? How far the cars would be if they travelled in opposite direction?

A particle A is at origin and particle B is at distance y=-d at t=0. They move with constant velocity v , A towards positive x-axis and B towards origin. The time at which distance between them is minimum and minimum distance will be
