Question

The map scale which uses different units of measurement on the right-hand side
and the left-hand side.

Answer 1

Answer:

The only difference is that we have to use the units given in the verbal scale (e.g., 1 inch to 17 miles). We'd probably want to measure our ..

Here u go

Explanation:

1. Verbal Scale: The verbal scale is just a sentence stating that "1 Map Unit = X Land Units". For reasons of convenience, a mixture of units is commonly used, such as

1 inch  = 1 mile

However, there are NO requirements that the units must be different! The expression "1 inch = 63,360 inches" is still a verbal scale. A mixture of map and land units makes the verbal scale difficult to compare between different maps - it must be converted first to a Representative Fraction (see below).

2. Representative Fraction (R.F.): An R.F. scale is a ratio, or fraction, that expresses the mathematical relationship between MAP and LAND, such as

1 : 24,000

which means "1 map unit is equivalent to 24,000 land units." Because an R.F. carries no units (inches, centimeters, etc.), it means that the R.F. scales can be compared between different maps. Converting an R.F. scale to a verbal scale is very easy; simply select ONE unit and apply it to BOTH map and land numbers. The above example can be written as a verbal scale as "1 inch = 24,000 inches" or "1 meter = 24,000 meters," etc. (Note: YOU CANNOT MIX UNITS in an R.F.! Doing so will change the numerical relationship of the R.F.)

3. Graphic Scale: The graphic scale is a bar chart or "ruler" that is drawn at the bottom of a topographic map. This is the scale that you should use when asked to measure distances on the map. Be Careful: Note that the zero mark is not located at the left end of the graphic scale. For your convenience, the graphic scale extends to the left of the zero mark to indicate fractions of units, such as 1/10 of a mile. You may measure distances by marking off the 2 end points on the edge of a sheet of paper and aligning the edge of the paper against the graphic scale (make sure one of your marks is on the zero).
