□ hours per dollar
(b) amy runs 5 miles in 40 minutes.
how many minutes does she take per mile?
□ minutes per mile

Explanation:

Step1: Solve part (a)

To find hours per dollar, divide total hours by total dollars.
Total hours = 5, Total dollars = 18.
So, \( \frac{5}{18} \approx 0.28 \) (rounded to nearest hundredth).

Step2: Solve part (b)

To find minutes per mile, divide total minutes by total miles.
Total minutes = 40, Total miles = 5.
So, \( \frac{40}{5} = 8 \).

Answer:

(a) \( \boldsymbol{0.28} \) hours per dollar
(b) \( \boldsymbol{8} \) minutes per mile
