Answer 2

Speed and velocity are both measured using the same units. The SI unit of distance and displacement is the meter. The SI unit of time is the second. The SI unit of speed and velocity is the ratio of two — the meter per second.

This unit is only rarely used outside scientific and academic circles. Most people on this planet measure speeds in kilometer per hour (km/h or kph). The United States is an exception in that we use the older mile per hour (mi/h or mph). Let's determine the conversion factors so that we can relate speeds measured in m/s with the more familiar units.

1 kph = 1 km 1000 m 1 hour

1 hour 1 km 3600 s

1 kph = 0.2777… m/s ≈ ¼ m/s

1 mph = 1 mile 1609 m 1 hour

1 hour 1 mile 3600 s

1 mph = 0.4469… m/s ≈ ½ m/s
