Answer:Hi, the correct answer is $\frac{160}{3}$ .

Step-by-step explanation:

As you are being asked for rate and the importat value is the number of calories consumed. We need to simplify the fraction $\frac{480 calories}{9 ounce}$ . Then we simplify.

Note that 480 is divisible by 3 and 9 as well. 480/3 = 160 and 9/3 = 3. Therefore, 480/9 = 160/3.
