Question

Suppose a car's standard tires are replaced with tires 1.30 times larger in diameter.(i) Will the car's speedometer reading be (a) 1.69 times too high,(b) 1.30 times too high,(c) accurate,(d) 1.30 times too low,(e) 1.69 times too low, or (f) inaccurate by an unpredictable factor?

Answer 1

The answer is 1.30 times too low.

What is a speedometer reading?

• According to the law, speedometers can never understate a vehicle's speed while never exceeding 110% of the real speed + 6.25 mph. Therefore, if you're traveling at 40 mph, your speedometer may display up to 50.25 mph, but it will never show a speed below 40 mph.
• While the speedometer displays how fast your car is moving, the odometer displays how far it has traveled. According to Tetzlaff, the speedometer's accuracy in most cars, including Volkswagens, is typically within a few percentage points of actual speed.
• A car's speedometer is a tool that displays the vehicle's speed. An odometer is yet another accessory connected to a speedometer. The car's odometer displays the distance driven. The speedometer, as we all know, displays the pace of every single moment.
• Federal law prohibits speedometers from having an inaccuracy of more than 5% (usually stated as plus/minus 2.5% relative to the real speed), according to Dan Edmunds, an automotive engineer and director of vehicle testing at Edmunds.com.

The answer is 1.30 times too low.
