Question

Hazel is training for an Ironman Triathlon and completed two swimming workouts this week. On Sunday, she swam 812 yards in 11 minutes and 38 seconds. This morning, she swam 619 yards in 8 minutes and 2 seconds. What was Hazel's average speed over the two workouts?

Answer 1

The average speed over two workouts is 1.22375 yards per second.

The formula is S = D/T

The first workout had a total time of 698 seconds and a distance of 812 yards. 812/698= 1.1633 yards per second.

The second workout had a total time of 482 seconds and a distance of 619 yards. 619/482=1.2842 yards per second.

1.1633 + 1.2842 = 2.4475 / 2 = 1.22375 yards per second.
