Question

On a map, Roseville and smith town are 5 1/2 inches apart If the actual distance between the town is 16 1/2 miles, to what unit rate is the map drawn

Answer 1

Answer: The unit rate = 3 miles per inch.

Explanation:

Given: Distance on map =
`5\frac12` inches
`=(11)/(2)` inches

Actual distance =
`16\frac12` miles
`=(33)/(2)` miles

That means 1 inch on map =
`((33)/(2))/((11)/(2))\ miles`

`=(33)/(2)\ miles`

`=3\ miles`

Hence, the unit rate = 3 miles per inch.
