“Thereisamap…inthecockpit…themonitor…lookat themonitor,”thepilot manages to say before he faints. He is too weaktostay conscious verylong but you go to the cockpitand find the map and the monitorwhich you can use to find your location.
Youandyourteammateslookatthemap. “Wherearewe? Italllookslikeforestto me,”sayssomeone.
Maria,whoactuallypaidattentioningeographyclass,speaksup.“Well,wecan seeourlatitudeandlongitudeonthemonitor.Itshowsusexactlywhere we arebyusing the GlobalPositioningSystemsatellites in the sky.Now we can figure out where we are on the map, where we want to go and how far away itis!” Everyonelooksatthemaphoping thenearestcityisn’tveryfaraway.
Procedure:
On the next page is a map of the Amazon around the area that you have crashed. Notice thescale,thekey,andthelatitudeandlongitudemarkingsonthemap.Usingthelatitude and longitudevaluesgivenin the boxbelow, markan X on the spot where you have crashed.(Hint: Trace alongthe latitudeand longitudelinesto helpyoufindthe exactcrash location.)
Latitude:2½°S Longitude:60°W
1.To be rescued,do youwant to go toa (Hint: there could be more than one answer):
City?
Village?
Airport?
2. Use the legendon the map to help you decidewhere youwant to go andmarkthespot on themapwith an O.
Record the name of whereyouwanttogo
3.AddtheX andtheOsymbolsto the legend.Then, use a ruler to draw adotted line
betweentheX andthe O onyourmap.
4.Measure the length of the dotted line in inchesand record it below.
5. Convert thelengthfrominchesto miles(Hint: you’llwant to usethe conversionfactor of
5280 ft/mile)and record your answer below.
6. As a class,voteon a route that youallwill follow.If the route chosen by the class is differentthantheoneyouchoseearlier,draw the new route on your map in a solidline. Repeatsteps#4and#5forthesolidlineandrecordyourresultsbelow.
Length of solid line:

EstimatingtheTimeofTravel:
Now that you know how far you will be traveling, you will need to estimatethe time it will taketoreachyourdestination.Use thetablesbelow to helpyouplanfor your journey.
Table1:WalkingSpeeds
Weight carried / Walking Speed0 – 23 lb. / 3 mph
24 – 46 lb. / 2 mph
47 – 70 lb. / 1 1/2 mph
1. Use Table1 to findyourwalkingspeed.Note that the speedyoucantraveldependson howmuchyouarecarrying.Fornow,assumeyouarecarrying45lb.
What is yourwalkingspeed?
Table2:SpeedandDistance
Speed / 3 mph / 2 mph / 1.5 mphNormal day’swalk / 24 miles / 16 miles / 12 miles
2. UseTable2tofindouthowmanymilesyoucanwalkinanentireday.Thischart assumesyouwillwalkforabout8hours.MatchyourwalkingspeedfromQuestion1to find your total milesper day.
How far can you normally walk inaday?

4. Using the numberof mileswalkedin a day(from Question2), findthedistance youcan travelinadaybyfollowingthedirectionsunder“speedmodifier”.
How farcanyoutravelinthe forest in aday? How far can you travel on theriverina day?
5. UsingtheTables1,2,and3,estimatehowlongitwilltakeyoutoreachyour destination.Calculate the speed and time for each part of the trip in the box provided below (i.e. for each type of terrain.)Show your work.
