The constant of proportionality in the equation y=7.5x is 7.5. This constant represents the number of minutes Chaquille spends running per mile. More specifically, according to this direct variation equation, Chaquille runs each mile in 7.5 minutes.
Therefore, the correct response is:
The constant of proportionality is 7.5. Chaquille runs each mile in 7.5 minutes.
Chaquille can run 3 miles in 22.5 minutes. The direct variation equation y=7.5x gives the relationship between y, the number of minutes Chaquille spends running, and x, the number of miles he runs.
