When my car has wheels with a diameter of 24 inches, its speedometer reports the correct speed of my car. I recently replaced my 24-inch wheels with 28-inch diameter wheels. I didn’t change my speedometer, however. When the speedometer tells me that the car is going 40 miles per hour (and I’m driving with my 28-inch wheels), how fast is my car really going?

The post above is not the correct solution for this question.

The circumference of the wheels is proportional to the ** square** of the radius.

\(\dfrac {28^2}{24^2} * 40 =\)
