Question

terrell has a water purifier for backpacking. it will purify 1 liter of water in 1 min. how long would it take terrell to purify enough water for 4 canteens that each hold 750 mL, and two that each hold 1.5 L

Answer 1

It would take 6 minutes to purify enough water.

Explanation:

Water purifier will purify 1 liter of water in 1 minute.

Terrell needs enough water for 4 canteens that each hold 750 ml.

Water for 4 canteens = 750 ml × 4 = 3000 ml = 3 liters

water for 2 canteens = 1.5 L × 2 = 3 liters

Water for total canteens = 3 + 3 = 6 liters.

Now it is given that water purifier will purify 1 liter of water in 1 minutes so 6 liters of water will purify in 6 minutes.

Answer 2

4 × 750 = 3 L so it will take 3 minutes for 4 canteens and
2 × 1.5 = 3 L it will also take 3 minutes
total it will take 6 minutes.
