Answer 2

A speedometer or a speed meter is a gauge that measures and displays the instantaneous speed of a vehicle. Now universally fitted to motor vehicles, they started to be available as options in the 1900s, and as standard equipment from about 1910 onwards.[1] Speedometers for other vehicles have specific names and use other means of sensing speed
An odometer or odograph[1][2] is an instrument used for measuring the distance travelled by a vehicle, such as a bicycle or car. The device may be electronic, mechanical, or a combination of the two. The noun derives from the Ancient Greek words hodós ("path" or "gateway") and métron ("measure"). Early forms of the odometer existed in the ancient Greco-Roman world as well as ancient China
