One of the marathon runners claims that the refreshments stations are two times the number of medical stations. With calculations prove whether this statement is valid or not.

Step 1: Count the number of refreshment stations. From the map legend, refreshment stations are marked with a blue circle (•). Counting them on the route: 18 refreshment stations. Step 2: Count the number of medical stations. From the map legend, medical stations are marked with a red cross inside a circle (⊕). Counting them on the route: 2 medical stations. Step 3: Check the claim: "refreshment stations are two times the number of medical stations". Number of refreshment stations = 18 Number of medical stations = 2 According to the claim, Refreshment Stations = 2 × Medical Stations. 18 = 2 × 2 18 = 4 Since 18 ≠ 4, the statement is not valid. The statement is not valid. You've been here a while — type /upgrade for unlimited. Cancel anytime.
