Step-by-step explanation:
The speed of the tires (v) is the same that the speed of the car, so to find the angular velocity of the tires we need to use the equation:

Where:
r: is the radius of the tires = d/2 = 28 inches/2 = 14 inches
Therefore, the tires are spinning at 660.49 revolutions per minute.
