Question

два одинаковых насоса выкачивали из подвала воду. Первый насосработал 12 мин,второй- 16 мин,и он выкачал на 4320 л воды больше, чем первый.Сколько литров воды выкачал каждый насос?

Answer 1

1) 16-12=4(мин) разница
2) 4320:4=1080(л) - за 1 минуту
3) 12*1080=12960(л)
4) 16*1080=17280(л)
Ответ: 1 насос 12960 л, 2 насос 17280 л

Answer 2

16-12=4мин разница
4320:4=1080(л) в минуту
1080*12=12960(л) 1 насос
1080*16=17280(л) 2 насос

Answer 3

Calculating Water Pumping Capacity

To calculate the amount of water pumped by each pump, we can use the following approach:

Let's assume the first pump's pumping capacity is represented by x liters per minute and the second pump's pumping capacity is represented by y liters per minute.

Given: - The first pump worked for 12 minutes. - The second pump worked for 16 minutes. - The second pump pumped 4320 liters more than the first pump.

We can set up the following equations based on the given information:

1. The amount of water pumped by the first pump: 12x liters 2. The amount of water pumped by the second pump: 16y liters 3. The second pump pumped 4320 liters more than the first pump: 16y = 12x + 4320

We can use these equations to solve for the values of x and y.

Solving for Pumping Capacities

To find the values of x and y, we can use the given information to set up and solve a system of equations.

First, we can use the equation 16y = 12x + 4320 to express one variable in terms of the other: y = (3/4)x + 270

Now, we can substitute this expression for y into the equation for the amount of water pumped by the second pump: 16((3/4)x + 270) = 12x + 4320

Solving for x: 12x + 4320 = 12x + 4320 12x = 12x This equation shows that the value of x can be any real number, as it cancels out on both sides. This means that the value of x cannot be determined from the given information.

Without additional information about the pumping capacities of the two pumps, it is not possible to determine the exact amount of water pumped by each pump.
