Question

On a treasure map, the route is 3 inches north, 2 inches west, 1.5 inches north, and 0.25 inches east. The actual distance of the entire route is 135 feet. What does each inch on the map represent? Explain how you found the answer.

Answer 1

Add the map lengths: 3 + 2 + 1.5 + 0.25 = 6.75 inches on the map.
If 6.75 in corresponds to 135 ft in reality, then each inch represents 135 ÷ 6.75 = 20 feet.

So 1 inch on the map = 20 feet in reality.
