Question

An Olympic cyclist rides round a velodrome track 5 times. The diagram below shows the reading on the stopwatch which was used to time the laps. Unfortunately, the person using the stopwatch started it a little early. What is the average time to complete one lap of the velodrome? A. 15.21 s B. 14.04 s C. 15.84 s 2.00 s 14.04 s 81.21 s D. 14.21 s At the After At the end of slart one circuil five circuitsSHOW LESS83

Solution

C. 15.84 s.

To find the average time to complete one lap of the velodrome, we need to find the total time taken for the 5 laps and then divide it by 5. Looking at the diagram, we can see that the stopwatch started at 2.00 s and ended at 81.21 s after 5 circuits.

To find the total time, we subtract the starting time from the ending time: 81.21 s - 2.00 s = 79.21 s.

Then, we divide the total time by the number of laps: 79.21 s / 5 = 15.84 s.
