Suppose a car's standard tires are replaced with tires 1.50 times larger in diameter. Will the car's speedometer reading be

The speedometer measures the number of revolutions per second of the tires. A larger tire will rotate fewer times to cover the same distance. The speedometer reading is assumed proportional to the rotation rate of the tires, $\omega$ = $\frac{v}{R}$, for a standard tire radius R, but the actual reading is $\omega = \frac{v}{(1.5)}R$ , or 1.5 times smaller. Example: When the car travels at 15 km/h, the speedometer reads 10 km/h.
