A map has a scale of 1 inch:50 miles. If two schools are 3 inches apart on the map, how many miles apart are they in reality?

Question

Conversions and Scale Factor

since im a tutor in eighth grade i only know so much and were both stuck on this question it gave us a bunch of answers and the answers were 150, 3, 50, 200.

Answer 1

Since you already know 1 inch is to 50 miles and you are given 3 inches as the distance between the two schools, you can think of how many times you multiplied 1 inch by to get to 3 inches or what you divided 3 inches by to get to 1 inch. Once you figure out that number is 3, you can multiply it by 50 miles to see how many miles between the two schools.

Answer 2

A map has a scale of 1 inch:50 miles. If two schools are 3 inches apart on the map, how many miles apart are they in reality?

This can be solved using a proportion. We know one inch is equal to 50 miles. If the schools are 3 inches apart, multiply the number of inches (3) by the number of miles one inch represents (50).

So they are looking for the answer to 3x50

I hope this helps!
