Answer:
15 miles
Step-by-step 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
I don't think it is linear b/c i don't think you can plug in the numbers and get it to work. This may not be right though b/c I did this in my head.
