Practice question
Question
A bus is moving with a speed of 10 m/s 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?
Explanation
Scooter must cover initial 1000 m separation plus distance bus travels in 100 seconds. Bus covers 10 into 100 equals 1000 m. Total 2000 m in 100 s requires 20 m/s. Relative velocity concept yields same result.
