It doesn't.
A speedo only measures the speed you're travelling at, at that particular moment.
But you can get distance, if you stay at an even speed, and keep track of how long you've been going. Speed x time = distance. One hour at 50 MPH means 50 miles travelled. 1/2 hour at 50 MPH means 25 miles travelled.

A speedometer measures speed, not distance. It calculates the vehicle's speed by measuring the rotation of the vehicle's wheels and displaying this information on a gauge in the dashboard. Distance traveled can be calculated using speed and time, but a speedometer itself does not directly measure distance.
No, a speedometer is used to measure the speed or velocity of an object in motion, usually a vehicle. It does not measure force directly. Force is typically measured using instruments such as a dynamometer or a force gauge.
The speedometer of a car measures the speed at which the vehicle is traveling in miles per hour (mph) or kilometers per hour (kph). It provides the driver with real-time information about the vehicle's speed.
A commonly used device to measure the speed of a moving body is a speedometer. It measures the instantaneous speed of a vehicle by calculating the rotational speed of the wheels and converting it into a speed reading. Other methods such as radar guns or GPS devices can also be used to measure speed accurately.
Tape measure: used to measure distances and lengths. Scale: used to measure weight or mass. Thermometer: used to measure temperature. Ruler: used to measure small lengths or distances. Stopwatch: used to measure time or duration.
You can measure very large distances, such as the size of the observable universe or distances between galaxies, using yottameters. This unit of measurement is rarely used in practical applications due to its extremely large scale.
