Mathematics for IGCSE & O level - Limits Of Accuracy (Section 2 - No. 20)

A runner completed a 100m race in 12.3 seconds. What is the upper bound of their average speed?

8.04 m/s

8.06 m/s

8.10 m/s

8.14 m/s

Explanation

Upper bound speed = Upper bound distance / Lower bound time. The upper bound distance is 100.5m and the lower bound for time is 12.25. Then 100.5/12.25 = 8.21 m/s.
