Measure the distance on the map. Then, create a proportion.
380 kilometers
Practice makes perfect
We are given that the scale of a map is 1.5cm: 100km. To find the actual distance between Guymon and Oklahoma City, we will create a proportion.
1.5/100=distance on a map/actual distanceAfter measuring the distance using a ruler, we can see that cities are 5.7 centimeters apart on the map. Let's substitute this value into the proportion. Let x represent the actual distance.
1.5/100=5.7/x
Now we will solve the above proportion for x using cross multiplication.
