Mathematics for IGCSE & O level - Limits Of Accuracy (Section 1 - No. 21)
Two stages of a relay race are run in times of 14.07 seconds and 15.12 seconds, both to the nearest 0.01 second. What is the upper bound of the total time for these two stages?
29.19 s
29.2 s
29.20 s
29.21 s
توضیح
Upper bound of 14.07 s = 14.075 s. Upper bound of 15.12 s = 15.125 s. Total = 14.075 + 15.125 = 29.20s
