Explanation:

cuz he run 3.5 miles in 30 minutes (0.5 hours). So his speed is:

d = 7.5 mi/h × 2 h

d = 15 mi

Answer 2

15 miles

Explanation:

Steve runs 3.5 miles in 30 minutes (0.5 hours). So his speed is:

r = 3.5 mi / 0.5 h

r = 7 mi/h

If his rate increases to 7.5 mi/h, the distance he runs in 2 hours is:

d = 7.5 mi/h × 2 h

d = 15 mi
