Mathematics for IGCSE & O level - Limits Of Accuracy (Section 1 - No. 6)
Calculate, to 3 significant figures, the upper bound of the distance travelled for a speed of 92.4km/second for 12.3 seconds, both values to 3 s.f.
1130 km
1132 km
1132.1 km
1133 km
Forklaring
The lower bound of the speed is 92.35 and the upper bound of the time is 12.35. Upper bound of the distance = 92.35 * 12.35 = 1139.7 km
