Question

The legend on a map reads 1.25 inches represents 500 miles. If the measurement on the map between two locations is 3 inches, how far apart are they? Show your work.

Answer 1

These two locations are 1200 miles apart.

Explanation:

This question is solved using proportions, by a rule of three.

We have that:

1.25 inches represents 500 miles. 3 inches will represent x miles. So

1.25 inches - 500 miles

3 inches - x miles

Applying cross multiplication:

`1.25x = 500*3`

`1.25x = 1500`

`x = (1500)/(1.25)`

`x = 1200`

These two locations are 1200 miles apart.
