Jill is using a map of her town to determine how far the park is from school. The map does not have a scale, but Jill knows her school is 3 miles from home. On the map, the distance between home and school measures 1.5 inches. If the park is 2.5 inches from the school on the map, what is the actual distance in miles?

The answer is five miles.

Step-by-step explanation:

Here’s one way to solve this problem.

First, write the ratio of the known distance on the map to the corresponding actual distance, one point five inches over three miles.

Next, choose a variable, such as d, to represent the unknown distance between the school and the park.

Then, write the ratio of the distance from the park to the school on the map to the corresponding actual distance, two point five inches over d miles.

Next, write a proportion equating the two ratios.

Now, cross multiply.

Finally, divide both sides by one point five to arrive at the actual distance, five miles.

So, the actual distance between the park and the school is five miles.

5 miles!
