On a scale drawing of oak grove, two landmarks are shown in 5 inches apart. These two places are actually separated by 35 miles. What is the map's scale? 1 inch = how many miles?
To find the map's scale, we need to determine how many miles are represented by one inch on the scale drawing.
If 5 inches on the map represent 35 miles in reality, we can set up a proportion to find the scale:
5 inches on map ------ 35 miles in real life
1 inch on map -------- x miles in real life
Cross multiplying, we get:
5 * x = 35
x = 35 / 5
x = 7
Therefore, the map's scale is 1 inch on the map represents 7 miles in real life.
