On a map, if the scale is 4 inches equals 24 miles, how far apart are two cities measuring 14 inches apart on a map?

So, if a scaled distance of 1 inch = 8 miles, how much is 2.4 inches, computes as 2.4 inches X 8 miles per inch = 19.2 miles. (Probably closer to 20 miles if allowing for changing elevations in the distance covered.) Note that the units operate just the same as the numerical magnitudes. If the units of the answer aren’t right, the formula isn’t right. Not really Rocket Science, but an important concept.

In elementary school, we used to refer to this as a Ratio Problem; two (2) equal ratios with one containing an unknown: ( note the operation on the units is as on the corresponding numbers)
