Question

Joanne has a map of her state with a scale in which 3 inches represents 100 miles . she has found that paxton and wheeldon are 7 1/2inches apart on this map. which is closest to the actual distance between these cities?

Answer 1

We will solve as follows:

*First: We take the 7 integers and 1/2 inches into fraction notation, that is:

$7\frac{1}{2}=\frac{14}{2}+\frac{1}{2}=\frac{15}{2}$

*Second: We will use the conversion factor to solve, that is:

$x=\frac{(\frac{15}{2})(100)}{3}\Rightarrow x=250$

From this, we have that the cities are 250 miles apart approximately.
