Mathematics for IGCSE & O level - Limits Of Accuracy (Section 1 - No. 50)

Find the lower bound of the sum of 11.04s and 13.46s (both to the nearest hundredth of a second).

24.49 s

24.50 s

24.505 s

24.51 s

Lower bound of 11.04 = 11.035. Lower bound of 13.46 = 13.455. Sum = 11.035 + 13.455 = 24.49
