A man walks 15 blocks to work every morning at a rate of 2 miles per hour.
If there are 20 blocks in a mile, how long does it take him to walk to work?
-----
Use a proportion:::
x miles/15 blocks = 1 mile/20 blocks
---
x = 15/20 = 3/4 miles
---
15 blocks is 3/4 miles
==========
time = distance/rate
time = (3/4) miles/ 2 mph = (3/4)(1/2) = 3/8 hrs = 22.5 minutes
=================

C) 22 1/2 minutes
