Mathematics for IGCSE & O level - Limits Of Accuracy (Section 2 - No. 40)

Two stages of a relay race are run in 14.07 seconds and 15.12 seconds. Both were measured to the nearest 0.01 second. What is the upper bound of the difference in those times?

1.03 s

1.04 s

1.05 s

1.06 s

Explanation

Maximum difference = Upper bound of 15.12 - Lower bound of 14.07. = 15.125-14.065=1.06. (1.03 to two d.p).
