Answer: The number of miles is 21 miles that the team member jog.
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":
![Distance=Speed* Time](https://img.qammunity.org/2020/formulas/mathematics/high-school/7p6j8170su8mh45t8eo7wx2fhgav8rzp53.png)
Number of miles of the team member is given by
![Distance=3.5* 6\\\\=21\ miles](https://img.qammunity.org/2020/formulas/mathematics/middle-school/sggg53t907mluuffzo3dne33hdwncd8j10.png)
Hence, the number of miles is 21 miles that the team member jog.
