If the distance was 300 kilometers and it took you 5 hours to cover it, your speed was 300 / 5 60 km/h (kilometers per hour). If the total distance travelled was 500 miles and the time it took you was 5 hours, then your average speed was 500 / 5 100 miles per hour (mph). The average walking speed of an adult is 3 to 4 miles per hour, but that all depends on age, fitness level, terrain, and other factors. The following tables provide a summary of the Speed or Velocity units (Per Hour, Per Minute, Per Second and Per Millisecond) within their respective measurement systems. Make sure you subtract any rests or stops you made from the total trip duration.
