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 lower bound of the difference between the times for those two stages?
1.03 s
1.04 s
1.05 s
1.06 s
Explanation
15.115 - 14.075 = 1.04 (Rounded to two d.p it's 1.03). Therefore, it's 1.04s.
