Question

Buses ply on a route at 20m/s every 10 minutes. A car moves at 30m/s in the direction of the bus.The time interval at which the car meets the buses is 5x minutes. Find x​

Answer 1

Answer:

Since the two cars are moving in the same direction with same speed therefore relative speed between two cars is zero.

Let the relative speed of the third car be w.r.t the two cars.

Relative velocity of the third car:

(4/60)h

5km

=75km/h

Actual velocity of the third car:75−30=45km/h
