Question

on a map, 3 inches represent an actual distance of 42 miles. If the actual distance between two cities is 322 miles, how many inches apart will the two cities be on the map ?

Answer 1

3 INCHES= 42 MILES. 42 MILES DIVIDED BY 322 MILES= 7.6
3X7.6= 22.8 INCHES APART

Answer 2

Two cities are 23 inches apart on the map

Explanation:

on a map, 3 inches represent an actual distance of 42 miles.

the actual distance between two cities is 322 miles

Let x be the inches apart on the map

Lets make a proportion

`(inches)/(actual) =(inches)/(actual)`

`(3)/(42) =(x)/(322)`

Cross multiply and solve for x

`966= 42x`

Divide both sides by 42

x= 23

Two cities are 23 inches apart on the map
