Answer:
There are quite a number of units to measure speed and depending on how fast an object is going, some are more preferred than others.
The units are:
- Metres per second - this is on of the most common units and is regularly used by runners.
- Kilometres per hour - used by cars, buses and generally objects that move adequately fast.
- Miles per hour - this is a substitute to kilometers per hour for countries using the imperial system or miles instead of kilometers.
- Knots - Represent nautical miles and are a unit of speed mostly used to measure wind and water speed.
- Feet per second - Not as popular but used in countries that don't regularly use metres.
- Mach number - for really fast objects going faster than sound.
