Question

What’s the actual distance = yards?

Answer 1

120 yards

A map scale is a ratio.

1 inch : 30 yards

Multiply both sides of the ratio by 4.

4 * 1 inch : 4 * 30 yards

4 inches : 120 yards

Answer 2

So we know 4 inches is 120 yds

Explanation:

We can use ratio's to solve this problem

1 inch 4 inch

------------ = --------------

30 yds x yds

Using cross products

1 * x = 30*4

x = 120

So we know 4 inches is 120 yds
