Julie swam, biked, and ran in a 22.2 mile triathlon. She completed the race in

2.15 hours. The function m = 13.8h represents the miles m Julie biked in

h hours. Was her average speed biking less than or greater than her average

speed for the entire race? Justify your answer. Round to the nearest tenth if

necessary.

Respuesta :

Average speed of biking is greater than average speed for the entire race.

Step-by-step explanation:

Total distance Julie traveled in triathlon = 22.2 miles

Total time taken = 2.15 hours.

We have

             Total distance = Average speed x Time taken

             22.2 = Average speed x 2.15

             Average speed = 10.33 miles per hour.

We also have the function m = 13.8h represents the miles m Julie biked in h hours. This is also similar to

                    Total distance = Average speed x Time taken

                     m = 13.8 h

             Average speed of biking = 13.8 miles per hour.

Average speed of biking > Average speed for the entire race

Average speed of biking is greater than average speed for the entire race.
