Water stations are to be arranged after every 500 m. How many water stations must be set up? At what positions from the starting point will these water stations be placed?
Given: Race distance = 3 km, Water station interval = 500 m
Step 1: Convert 3 km to metres 3 km = 3000 m
Step 2: Calculate number of water stations 3000 ÷ 500 = 6
Answer: 6 water stations (or 5 if not counting the finish line)
Positions from starting point: 500 m, 1000 m, 1500 m, 2000 m, 2500 m, 3000 m
Explanation
The chapter presents a practical problem about organizing a 3-km race. Students calculate how many water stations are needed if placed every 500 m.
Solution Steps
Step 1: Convert 3 km to metres: 3 km = 3000 m
Step 2: Divide total distance by interval: 3000 ÷ 500 = 6
Step 3: Water stations at positions: 500 m, 1000 m, 1500 m, 2000 m, 2500 m, 3000 m
