Answer:
152x miles
Step-by-step 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
