A bus is moving with a speed of 10 ms–1 on a straight road. A scooterist wishes to overtake the bus in 100 s. If the bus is at a distance of 1 km from the scooterist, with what speed should the scooterist chase the
bus?
-
- 40 ms–1
- 25 ms–1
- 10 ms–1
- 20 ms–1
Correct Option: D
Let v be the relative velocity of scooter
w.r.t bus as v = vs– vB
v = 1000/100 = 10ms-1vB = 10ms-1
∴ vS = v + vB, 
= 10 + 10 = 20 ms-1
∴ velocity of scooter = 20 ms-1
