what is the actual distance from oscars campsite to the general store?
□ mi
1 in. : 2 mi

Step1: Determine the scale - factor

The scale is 1 in. = 2 mi. So the number to multiply each length on the map by to find the actual distance is 2.

Step2: Find the actual distance

The distance from Oscar's campsite to the general store on the map is 3 in. Multiply the map - distance by the scale - factor. The actual distance $d=3\times2$.
$d = 6$ mi

Answer:

The number to multiply each length on the map by is 2. The actual distance from Oscar's campsite to the general store is 6 mi.
