Calculating Water Usage and Remaining Water in the Barrel

To calculate how many days the water in the barrel lasted and how much water is left, we can use the information provided.

- The barrel initially contains 65 liters of water. - 3 liters of water are taken in the morning, and 6 liters are taken in the evening.

To find out how many days the water lasted and how much water is left, we can calculate the daily water usage and the remaining water.

Days the Water Lasted

The total daily water usage is 3 liters + 6 liters = 9 liters.

To find out how many days the water lasted, we can divide the initial amount of water in the barrel by the total daily water usage: 65 liters / 9 liters/day = 7.22 days.

The water lasted for approximately 7 days and a few hours.

Remaining Water

To find out how much water is left after 7 days, we can subtract the total water used from the initial amount of water: 65 liters - (9 liters/day * 7 days) = 65 liters - 63 liters = 2 liters.

So, after 7 days, there are approximately 2 liters of water left in the barrel.

Therefore, the water in the barrel lasted for about 7 days and a few hours, and there are approximately 2 liters of water left.
