The speedometer on a car calculates speed by determining the linear velocity of a point on the tire. A certain car's computer is calibrated to determine the speed of the car assuming it has wheels with a diameter of 26 inches. The car's owner puts a wheel on the car that have a diameter of 30 inches. If the wheel is spinning at 90 rotations per minute, how does the car's actual speed compare to speed that the speedometer reads?

The speedometer on your car is broken. However you notice that the wheels of your car are rotating at 675 rpm (that reading is not broken on your car). Being a number geek, you know that the radius of your tires is 12 inches = 30 cm. Calculate the speed of the car (this is the same as the velocity of the tire rims). Please show all math steps. Thanks!

The speedometer readings in passenger cars are based on angular speed of the car's tire axle. Because car's tires are filled with air [typically to the pressure of about 30 psi (pounds-square-inch)], the actual tire radius can be a bit different depending on the air temperature. You want to understand the impact of the air temperature on the tire radius and thus on the accuracy of the speedometer reading based on the ideal gas law. To simplify the calculation, you...
