a bus is moving with a speed of 10m/s on a straight road. a scooterist wishes to overtake the bus in 100 sec. if the bus is at a distance of 1 k from the scooterist , with what speed the scooterist chase the bus?
Can u tell why u took relative speed of scooter wrt bus to be 10m/s?
Let v, be the velocity of the scooter, the distance between the scooter and the bus = 1000 m, The velocity of the bus = 10 ms-1 Time taken to overtake = 100 s Relative velocity of the scooter with respect to the bus = (vs-10) :. 1000/(vs-10) = 100s = vs = 20 ms-1-on-in-100
