Question

The Natchez Trace Bridge in Franklin, Tennessee, is 1,500 feet long. Suppose you build a model of the bridge using a scale of 1 inch:25 feet. How long is the model? (Hint: 12 inches = 1 foot).
a.
5 ft
c.
7 ft
b.
6 ft
d.
8 ft

Answer 1

1/25 = x/1500 -- ( 1 inch to 25 ft = x inch to 1500 ft)
this is a proportion, so we will cross multiply
25x = (1)(1500)
25x = 1500 -- divide both sides by 25
x = 1500/25
x = 60 inches
60 inches = 5 ft (A)

Answer 2

thank you
