Remember:
A rate compares two quantities with different units; a unit rate has a second quantity of 1.
Find a unit rate by dividing the first quantity by the second.
A unit price is a unit rate that gives cost per item or per unit of measure.
The better buy is the option with the lower unit price when the units match.
At constant speed, distance equals rate times time.
