Answer 1

152x miles

Explanation:

Jose runs x miles per day each week for 5 days.

For 3 days of the week he runs at a speed of 8 minutes per mile. So we have

3*8*x = 24x

For 2 days he runs 7 minutes per miles. We have

2*7*x = 14x

in one week, he runs 24x + 14x = 38x

In 4 weeks, he runs

4*38x = 152x miles
