pat delivers newspapers every morning. On average She can deliver newspapers to 17 homes in 12 minutes.
a. if her normal route has 119 homes, how long does it take her to deliver the mail on average?
------
Use a proportion::
x/119 = 12/17
----
x = 119(12/17) = 84 minutes
-----------------------
b. when another deliverer is sick, Pat's route expands to a total of 155 homes. How long does this route take her?
x/155 = 12/17
x = 155(12/17) = 109.41 minutes
