Answer:
Step-by-step explanation:
Common examples of "unit rate" follow:
miles per hour (mph). How many miles are covered in 1 hour of driving?
25 cents/pen: each pen costs 25 cents each.
Suppose I know I can pack 1/4 box in 20 minutes. How many boxes can I pack in 1 hour? That would be a unit rate. To find it, write out the ratio
1/4 box 60 min
------------- and multiply this by the conversion factor ---------------
20 min 1 hour
... which results in 3/4 box per hour (a unit rate)
