Question: 1 / 400

If a map has a scale of 1:20,000 and you measure 5.5 inches on the map, what is the represented distance on the ground?

9,166.7 feet

To determine the represented distance on the ground from a map with a scale of 1:20,000, you can use the scale to convert the map measurement to actual ground distance.

The scale of 1:20,000 means that 1 unit on the map corresponds to 20,000 of the same units on the ground. Therefore, if you measure an object that is 5.5 inches on the map, you would first need to convert that measurement into a real-world distance.

1. **Convert inches to feet**: Since there are 12 inches in a foot, you would convert the 5.5 inches into feet by dividing by 12:

\[

5.5 \, \text{inches} \div 12 = 0.4583 \, \text{feet}

\]

2. **Apply the scale factor**: Now that you have the measurement in feet, you can multiply it by the scale factor (20,000):

\[

0.4583 \, \text{feet} \times 20,000 = 9,166.7 \, \text{feet}

\]

This calculation shows that a measurement of
