She thinks the speed is affected by the vehicle's weight? She thinks the transmission affects it? And, she can't solve this "puzzle"? This has to be fake. I sure hope so.
PS: She is actually somewhat correct about the tyre part, different size tires changes the ratio between actual speed at the wheels and speed shown on the speedometer since most cars measure speed from wheel travel and resistance. This problem is nonexistant in cars with the speedometers fixed to the transmission though, most cars with digital speedometers have the measurement taken directly from the driveworks and are heaps more precise.
