S & S Unit Test Review Part 2
A USGS 7.5 minute quadrangle map has a scale factor of 1:24000. This means that 1 unit on the map equals 24000 of the same units in the real world. Look at your map and answer the following questions.
1. One inch on your map equals how many inches in the real world?
2. One foot on your map equals how many feet in the real world?
3. One calculator length on the map equals how many calculator lengths in the real world?
4. Because it is hard to think about large numbers such as 24,000 inches, it would be nice if we could create a scale from the scale factor above that relates inches on the map to miles in the real world. Find the number of feet in 24000 inches below (round to the nearest hundredth).

5. In groups of 2-3, spread out you quadrangle map on your table. Imagine you are birds of prey and you are going to fly around searching for food. Look at the map and find 9 places you would like to hunt. List them below in the order that you would like to visit them with the first location being the starting point of your trip.
