Applications of Solving Equations Introduction and Summary This
chapter presents applications of material learned in the first
chapter. It shows how solving equations are useful when dealing
with word problems, rate problems, and mean average problems.
One of the most important applications of equations is in
solving word problems. Thus, the first section outlines the
steps to follow when dealing with a word problem. By breaking
them down into simple steps, word problems become less daunting.
The second section deals with a particular type of word
problems: rate problems. These problems deal with the
relationship between time spent traveling, rate of travel, and
total distance traveled. This section explain how to calculate
these numbers for a single traveler or for multiple travelers.
This is useful to know not only for textbook problems, but also
for real life--using the tools learned in this section, you can
calculate your own distances, times, and rate of travel. The
third and final section explains how t
