EXERCISE 7: PLOTTING A ROUTE ON A MAP Your airplane has made an emergency landing on the west side of the island. You have a map of the island that tells you there is a research station with water and a satellite phone on the east side of the island. 22. a. Plot (draw) a route from the plane to the satellite phone in one-mile segments, keep- ing the following rules in mind: . You travel two miles per day, in one-mile segments. Each one-mile segment must be a straight line, but they do not have to be the same direction. . You must drink fresh water from a freshwater stream, or pond at least once per day, but you have no way of carrying water with you. ● You are injured and cannot climb more than 30 feet in a mile. . Your injury prevents you from swimming or crossing rivers. b. In the table on the next page, you will be recording both the cardinal direction and the azimuth compass direction for each one-mile segment of your journey. (See Figure 2-7A and Figure 2-7B for a review of how to do this.) You will find an Azimuth Compass on page 207 of your lab manual. You will need scissors to cut it out. 23. What is the contour interval of your map? 24. How many days will it take for you to reach the satellite phone? 25. How many miles did you travel on foot? 26. If you had been able to travel a straight-line path to the satellite phone, how and days would it have been? miles many 27. What was the average gradient between the plane (which rests at sea level) and the phone?
