Question

The key on a map shows 3/8th of an inch is 60 miles. If two cities are 4 5/8 inches apart, what is this value in miles?

Answer 1

Answer: 740 miles

Step-by-step explanation:

You know that $\frac{3}{8}inches$ on the map is actually 60 miles and the distance between these two cities is $4\ \frac{5}{8}inches$.

You can express this distance as a decimal number:

$(4+0.625)inches=4.625inches$

Therefore, let be "d" the distance in miles between these two cities.

Then, you get:

$d=\frac{(4.625inches)(60miles)}{(\frac{3}{8}inches)}\\\\d=740miles$
