Question

ванну объемом 480 л можно наполнить горячей водой за 40 минут а холодной водой за 30 минут Сколько литров воды пропускает каждый кран за одну минуту

Answer 1

1) 480 ÷ 40 = 12 (л/мин) - пропускает кран с горячей водой

2) 480 ÷ 30 = 16 (л/мин) - пропускает кран с холодной водой

Ответ : кран с горячей водой пропускает 12 л в минуту, а с холодной - 16 л в минуту

Answer 2

To find out how many liters of water each tap can pass in one minute, we can use the concept of rates. Let's denote the rate of the hot water tap as "H" (liters per minute) and the rate of the cold water tap as "C" (liters per minute).

We are given two pieces of information:

1. The hot water tap can fill a 480-liter tub in 40 minutes.
2. The cold water tap can fill the same tub in 30 minutes.

Let's set up the equations for each tap:

1. Hot water tap: 480 liters ÷ 40 minutes = H liters per minute

2. Cold water tap: 480 liters ÷ 30 minutes = C liters per minute

Now, let's calculate the values:

1. Hot water tap: H = 480 liters ÷ 40 minutes = 12 liters per minute

2. Cold water tap: C = 480 liters ÷ 30 minutes = 16 liters per minute

So, the hot water tap can pass 12 liters of water per minute, and the cold water tap can pass 16 liters of water per minute.
