The second number in a unit rate is usually 1, although it can be the first.
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.
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.
unit rates are simple ex 3 candies cost 75 cents divide 75 by three the unit rate equals 25 cents
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.
