Measure the distance on the map. Then, create a proportion.
≈ 109 miles
Practice makes perfect
We are given that the scale of a map is 1inch: 125miles. To find the actual distance between Bangor and Portland, we can create a proportion.
1/125=distance on a map/actual distanceAfter measuring the distance using a ruler, we can see that the cities are 78 inches apart on the map. Let's substitute this value into the proportion. Let x represent the actual distance.
1/125=78/x
Now we will solve the above proportion for x using cross multiplication.
