Question

If 1 inch represents 10 miles on a map, then how many inches will represent 900 miles?

Answer 1

A simple way to find this using mathematical methods is to set up a proportion:

`(1)/(10) = (x)/(900)`

Then you would cross multiply getting:

900=10x (then divide by 10 on both sides to get the variable alone)

x=90

So 90 inches will represent 900 miles
