Question

nswer each part. If necessary, round your answers to the nearest hundredth.
(a) Ravi runs 3 miles in 26 minutes.
How many minutes does he take per mile?

(b) Teresa bought 10 pounds of sugar for 5.
How many dollars did she pay per pound of sugar?

Answer 1

(a) To find out how many minutes Ravi takes per mile, we can divide the total time by the total miles:

\[
\text{Minutes per mile} = \frac{\text{Total minutes}}{\text{Total miles}} = \frac{26 \text{ minutes}}{3 \text{ miles}} \approx 8.67 \text{ minutes per mile}
\]

(b) To find out how much Teresa paid per pound of sugar, we can divide the total cost by the total weight:

\[
\text{Dollars per pound} = \frac{\text{Total cost}}{\text{Total pounds}} = \frac{5 \text{ dollars}}{10 \text{ pounds}} = 0.50 \text{ dollars per pound}
\]

So the final answers are:
(a) Approximately 8.67 minutes per mile.
(b) 0.50 dollars per pound of sugar.
