Question

Решить задачу: За один час бассейн наполняется на 20% его объёма. Сколько времени потребуется, чтобы наполнить бассейн на 95%? Заранее спасибо!

Answer 1

Зависимость - прямая.
РЕШЕНИЕ
Составляем пропорцию
1 час : 20% = Х час : 95%
Преобразуем
0,2*Х = 0,95
Х = 0,95 : 0,2 = 4,75 час - время по задаче - ОТВЕТ

Answer 2

Problem Analysis

We are given that a swimming pool is filled at a rate of 20% of its volume per hour. We need to determine how much time it will take to fill the pool to 95% of its volume.

Solution

To solve this problem, we can set up a proportion using the given information. Let's assume the volume of the pool is represented by V.

The rate at which the pool is filled is 20% of its volume per hour. This can be expressed as 0.2V per hour.

We need to find the time it takes to fill the pool to 95% of its volume. This can be expressed as 0.95V.

Setting up the proportion, we have:

0.2V / 1 hour = 0.95V / t

where t represents the time in hours.

To solve for t, we can cross-multiply and solve for t:

0.2V * t = 0.95V * 1

Simplifying the equation, we have:

0.2t = 0.95

Dividing both sides by 0.2, we get:

t = 0.95 / 0.2

Calculating the result, we find:

t = 4.75 hours

Therefore, it will take approximately 4.75 hours to fill the pool to 95% of its volume.

Answer

It will take approximately 4.75 hours to fill the pool to 95% of its volume.
