Answer 1

First find the unit rate: 2,436 miles ÷ 6 days = 406 miles per day.

So the sentence can be completed as:
"The rate 2,436 miles / 6 days can be used to find the unit rate. This unit rate can then be used to find an equivalent rate that shows the time it takes to travel a total distance of [distance from the map] miles."

Using rate reasoning: if the trip is D miles (from the map), time (in days) = D ÷ 406. If you tell me the map distance between City A and City B, I will compute the number of days.
