Quizplus · Accepted Answer

The relationship between miles per gallon (mpg) and speed (s) can be described by the formula mpg = k/s, where k is a constant. Given that at 39 mph the car gets 26 mpg, we can find k by multiplying these two values (k = 26 * 39). To find the mpg at 67 mph, we divide this constant by 67 mph, resulting in approximately 15.1 miles per gallon.
