Question

A bus is moving with a speed of 10m/s on a straight road. A scooterist wishes to overtake the bus in 100s. If the bus is at a distance of 1km from the scooterist with what speed should the scooterist chase the bus?

Answer 1

let the speed of scooterist =x m/sec

speed of bus =10m/sec

relative speed =(x-10) m/sec

distance to be covered=1km=1000m

D=s×t

1000=(x-10)×100

x-10 =1000÷100=10

x=10+10=20m/sec
