Question

The legend on a map states that 1

inch is 80 miles. If you measure 6
inches on the map, how many
miles would the actual distance be?

Answer 1

`Actual = 480\ miles`

Explanation:

Given

`Map : Actual = 1\ in: 80\ miles`

Required

Find actual distance when map distance = 6 inches

Substitute 6 for Map in
`Map : Actual = 1\ in: 80\ miles`

`6\ in: Actual = 1\ in: 80\ miles`

Express as fractions

`(6\ in)/(Actual) = (1\ in)/(80\ miles)`

`(6)/(Actual) = (1)/(80\ miles)`

Cross Multiply

`Actual * 1 = 6 * 80\ miles`

`Actual = 6 * 80\ miles`

`Actual = 480\ miles`

Hence, the actual distance is 480 miles
