Fill in the missing values and/or information.
Problem: Larry and Maria have secured permission to hike cross country from the rangers. They have also secured permission to camp on the shore of Small Lake. The ranger station also provides a trail map. Larry and Maria notice the scale of the map is 1 inch = 0.25 mile. They draw a line due North on the map and draw another line to a point on the shore of Small Lake where they want to camp. How do they determine the direction they should travel and the distance they need to travel to reach this spot?
Solution: Larry and Maria use a ruler to determine the distance between the starting point and the campsite. The measure is 8.5 inches. They set up the equation:
= d:8.5. Thus, 8.5 inches on this map represents
miles.
To determine the direction of travel, Larry and Maria use a
that has a needle and a fixed arrow in a housing marked in
like a protractor. (From other math courses you should remember a protractor is an instrument in the shape of a semicircle marked to measure angles from 0o to 180o.)
Because North provides a
direction, Larry and Maria can use a compass to determine the
which represents the direction in which they should travel. The figure shows how they measured the angle of travel at
degrees.
