Confirm that the quantities are proportional in the following rates:

75 miles in 5 hours and 97.5 miles in 6.5 hours.

A. They are proportional.
B. They are not proportional.
C. Insufficient information to determine.
D. None of the above.

Answer :

Final answer:

The quantities are proportional.

Explanation:

Proportional quantities have a constant ratio between them. To determine whether the rates given are proportional, we need to calculate the ratio of miles to hours for each rate. For the first rate, 75 miles in 5 hours, the ratio is 75/5 = 15 miles/hour. For the second rate, 97.5 miles in 6.5 hours, the ratio is 97.5/6.5 = 15 miles/hour. Since both ratios are equal, the quantities are indeed proportional.
