5. Scale 1 : 24000
6. a. 1/2400 = 5/x, x = 120000cm, x = 1200 meters on ground
    b. 1/2400 = 5/x, x = 120000in, 1mile/63360 = x/120000, x = 1.89 miles on
        ground
    c. 1/2400 = x/63360, x = 2.64 inches on map

        60'/1º = 26/x, 3600''/1º = 17/x, x = 0.4333 + x = 0.0047 = 0.4380, 118.4380º
        West
        x/7.5 = 12.8/32, x = 3, 34º 7' 30'' - 3 = 34º 4' 30'' North
        60'/1º = 4/1, 3600''/1º = 30/x, x = 0.06667 + x = 0.00833 = 0.075, 34.075º

        60'/1º = 29/x, 3600''/1º = 56/x, x = 0.4833 + x = 0.0156 = 0.5 = 118.50º West
        x/7.5 = 30/32, x = 7.03125, 34º 7' 30'' - 7.03125 = 34º 0º 28'' North
        60'/1º = 0/x, 3600''/1º = 28/x, x = 0 + x = 0.0078 = 34.0078º North

        x/7.5 = 19/26.25, x = 5.4286, 118º 30' - 5.4286 = 118º 24' 34'' West
        60/1º = 24/x, 3600''/1º = 34/x, x = 0.4 + x = 0.00944 = 118.4094º West
        x/7.5 = 1/32, x = 0.2344, 34º 7' 30'' - 0.2344(60) = 34º 7' 16'' North
        60'/1º = 7/x, 3600''/1º = 16/x, x = 0.1166 + x = 0.0044 = 34.1212º North
