Question

Из неисправного водопроводного крана в секунду капают 2 капли а за 12 мин наполняется полный стакан. Сколько литров воды может зря вылиться из такого крана в течении часа? В течении суток? (Считать а литреи4 стаканов)

Answer 1

1)

1 час = 60 мин

60 ÷ 12 = 5 стаканов наберётся за 1 час;

5 ÷ 4 = 1,25 литров воды выльется за 1 час.

2)

24 часа = 1440 минут;

1440 ÷ 12 = 120 стаканов наберётся за сутки;

120 ÷ 4 = 30 литров воды выльется воды за сутки.

Ответ: за 1 час — 1,25 л, а за сутки 30 л.

Answer 2

Calculation of Water Leakage

To calculate the amount of water that can be wasted from a faulty faucet, we need to determine the number of drops per second and the time it takes to fill a glass.

Given: - The faulty faucet drips 2 drops per second. - It takes 12 minutes to fill a full glass.

To find the amount of water wasted in liters per hour and per day, we can follow these steps:

1. Convert the time it takes to fill a glass from minutes to seconds: - 12 minutes = 12 * 60 seconds = 720 seconds.

2. Calculate the number of drops that fall in 720 seconds: - 2 drops/second * 720 seconds = 1440 drops.

3. Convert the number of drops to liters: - 1 liter = 20 drops (according to the given conversion rate of 1 liter to 4 glasses). - 1440 drops / 20 drops = 72 liters.

Therefore, in the span of 1 hour, approximately 72 liters of water can be wasted from the faulty faucet.

To calculate the amount of water wasted in a day, we can multiply the hourly amount by 24: - 72 liters/hour * 24 hours = 1728 liters.

Thus, in the span of 1 day, approximately 1728 liters of water can be wasted from the faulty faucet.

Please note that these calculations are based on the given information and assumptions.
