The rate 1,218 miles over 3 days can be used to find the unit rate. 1,218 ÷ 3 = 406, so the unit rate is 406 miles per day. This unit rate can then be used to find an equivalent rate that shows the time it takes to travel a total distance of the number of miles from City A to City B (call that D). Time = D ÷ 406 days.

(If you substitute the map distance for D you get the number of days.)
