I explain what is a unit rate, and show how to find the unit rate from a non-unit rate, including when FRACTIONS are involved. For example, I find the unit rate when you walk 1/2 mile in 1/4 hour.
Then, I solve a word problem using the unit rate. Lastly, we look at a graphing problem that involves constant speed — the unit rate ends up being the speed, and also the slope of the line.
