To compare all the speeds must be in same units.
1/ Athlete speed, 10 m/s
2/ Cycle speed, 200 m/min = 200 m/60 sec = 3.33 m/s
3/ Scooter speed, 30 km/hr = 30 x 1000 m/ 3600 s = 8.33 m/s.
Hence, the arrangement of increasing order is,
2. a cycle moving wth a speed of 200 m/min.
3. a scooter moving wth a speed of 30 km/h
1. an athlete running at a speed of 10 m/s
