  1. 1:175, if 2ft= 350 ft in life 1ft feet would probably be 175. (Cross multiplication)
    6.a)100miles, 1 inch= 20mile so 5 inches multiplied by 20 miles gives you 100miles
    b) 10 inches from Appleton. 1inch:20miles  (cross multiply to get 10inches)
                                                     x   :200miles
    c)25000 miles will reach the equator so 50000 miles will go around the world! So, if 1inch:20miles,(50000/20=2500inches) And if 12inches:1ft, 2500inches 1ft/12 inches to get 208.33.
    7.a) 1inch:2.5miles(5inches    2.5miles/1) 5inches would be 12.5miles.
    b)1inch:2.5miles, 41miles?. (1inch*41miles/2.5miles=x) x=16.4, so 41miles=16.4inches
    c)No. Because they have different scales.
