An item travels 70 ft in 10 s. What is the unit rate?

Distance = (rate) (time)

if you want o find the rate you have to get in by itself on one side so divide both sides by time

distance/time = rate

now replace the words with the values and complete the problem

(70 ft) / (10s) = rate

7 feet per sec = rate

The answer is that the unit rate is 7 feet per sec (or fps)
