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.

Explanation:
School starts in a week so Aubrey and her grandmother go "back to school" shopping. Aubrey is not excited for school because she will not know anybody other than Bridget. Her and Bridget spend the last few days of summer playing outside. The first day of school is actually on Aubrey's little sister's birthday which makes it even worst. After the day is over Aubrey actually likes her new school.
Hope that helps
