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