Question

the legend of a map says that .5 inches is equal to 10 miles on a map. if a highway on a map is 1.75 inches long, how long is the actual highway

Answer 1

You are comparing inches to miles...

so set up a proportion:

inches is to miles...as inches is to miles


so your equation would be

.5/10 = 1.75/x (x is what you are looking for).

Answer 3

yep, easyaspi is correct, however you might wanna set up the ratios in reverse to make it easier to solve for x...
10miles/.5 inches = x miles/1.75 inches...

so x=(1.75)(10/.5) miles
