You measure the total distance the bike travels, and the total time it takes to travel that distance. You then divide the distance by the time
A watering can is used to hold a water that we will use to water the plants. The water has both mass and volume. Two watering cans are most often different by the volume they contain.
Many various units for volume are used but most often used unit is liter. In a metric system basic units are those such as meter, kilogram and liter while in imperial system units used are those such as foote, inch, pound and gallon.
Unit for volume in metric system is cubic meter. It is equal to a volume of a cube whose all sides measure 1m. This is equal to 1000L. For watering cans that contain several liters units used is decimeter cubed. 1dm^3 = 1L
Density of a material depends upon it's mass & volume.
You can calculate it by: Density = Mass / Volume

I believe it's 'A'. Hopefully this helps!~ :)
The starting point for measuring motion is called : The Reference Point.
