Question

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