Mathematics for IGCSE & O level - Limits Of Accuracy (Section 2 - No. 2)
Calculate, to 3 significant figures, the lower bound of the average speed for those measured times and distances. The distance travelled is 106 m in 10.0 seconds (both values to 3 s.f.)
10.5 m/s
10.55 m/s
10.6 m/s
10.7 m/s
Explanation
Lower bound of speed is distance/time = 105.5/10.05 = 10.5m/s.
