Question

On a​ map, 1 inch equals 5.2 miles. Two houses are 3.5 inches apart on the map. What is the actual distance between?

The actual distance between the house is miles?

Answer 1

18.2 miles

Explanation:

This can be solved using a very handy trick that can be worded as: "1 inch is to 5.2 miles as 3.5 inches are to x miles". Let x be the value in miles that we wish to find:

`1 < - > 5.2\\3.5 < - > x\\\\Fundamental-property-of-proportions:\\x = (5.2*3.5)/(1)=18.2`
