Answer: The number of miles is 21 miles that the team member jog.
Step-by-step explanation:
Since we have given that
Average jogging rate off the cross country team = 6 miles per hour
Time taken by one member per weekend = 3.5 hours
We need to find the "Number of miles the team member jog":
As we know the formula for "Distance-Speed":
[tex]Distance=Speed\times Time[/tex]
Number of miles of the team member is given by
[tex]Distance=3.5\times 6\\\\=21\ miles[/tex]
Hence, the number of miles is 21 miles that the team member jog.
