Answer 2

Answer:

20ms-1

Explanation:

Let the point at which the scooterist is initially situated be taken as the origin. At the start, the bus is at a distance of 1 km and moving away at the rate of 10 m/s. Let the speed of the scooterist be v m/s. In 100 seconds, the bus would be 2 km from the origin. So the scooterist will have to cover this distance in 100 seconds. His speed will then have to be 2/100 km/s of 20 m/s. So the scooterist should chase the bus at speed of 20 m/s or 72 km per hour.
