When you tell someone about your trip, he doesn't want to hear that you stayed on the
interstate most of the time and maintained 58 miles per 47 minutes, and that the car
averaged almost 19.5 miles per 83 ounces. It's a lot easier to say, easier to understand,
and easier to compare, if you reference your results to hours and gallons.

How are rates and unit rates different?
The second number in a unit rate is usually 1, although it can be the first.
Why are rates usually written as unit rates?
With unit rates there is only one number that needs to be remembered for the conversion factor.
What is the relationship between unit rates slopes and constant rate of change?
Unit rate, slope, and rate of change are different names for the same thing. Unit rates and slopes (if they are constant) are the same thing as a constant rate of change.
What are examples that are not unit rate?
When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. If you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
When a rate is written as money per item a unit rate is called?
