PROBLEM
The map's scale is 1 inch = 16 miles. If the distance is 243 inches, how many miles apart are the cities?
STEP 1
Assumptions1. The scale of the map is1 inch equals16 miles.
. The distance on the map between the two cities is 43 inches.
STEP 2
We need to convert the distance on the map to the actual distance. We can do this by multiplying the distance on the map by the scale of the map.
Actualdistance=DistanceonmaptimesScaleofmap
STEP 3
Now, plug in the given values for the distance on the map and the scale of the map to calculate the actual distance.
Actualdistance=23inchestimes16miles/inch
STEP 4
First, convert the mixed fraction to an improper fraction.
243=411Actualdistance=411inchestimes16miles/inch
SOLUTION
Calculate the actual distance.
Actualdistance=411inchestimes16miles/inch=44milesThe cities are44 miles apart.
