Answer:
6 hours
Step-by-step explanation:
We can think of this problem as a "work" problem and use the formula:
work = rate x time
Let p be the rate of a single pump. So the total rate of 3 pumps is 3p. And the total time is 8 hours, so the work needed to fill a pool is:
work = 3p x 8 = 24p
We need 24p to fill up a pool.
So what happens when you have 4 pumps? That is a rate of 4p. So how much time is needed to fill up a pool that requires 24p of work?
Solve by using the work = rate x time equation:
24p = 4p x t
6 = t
6 hours.

Answer:
<em>Question 3. Option B,</em>
<em>Question 4. Option D,</em>
<em>Question 5. Option B</em>
Step-by-step explanation:
Question 3.
If we have a table, we can note that each juice has a proportionality among one another - comparative to the number of servings. If we can figure out this proportionality, we can apply it to the servings of grapefruit juice;
As we can tell, this " proportion " is 1 to 2. Thus, the amount of grapefruit for 16 servings is 2 * 3 = 6c -<em> Option B</em>
Question 4.
The distance Carlos biked is 24 miles, the total distance he covered is 30 miles;
Question 5.
If 1 / 6 of the fruits are oranges, there must be 6 times of the other fruit. Thus, the solution is <em>Option B</em>

Answer:
The unit rate is $0.37 per popsicle.
Step-by-step explanation:
Unit rate represents the rate per one unit. In this case, the unit rate would represent the cost per popsicle. Since one box contains a total of 12 popsicles, we need to take the total cost of the box ($4.44) and divide by the number of popsicles that come in the box, or 4.44/12. When we divide, we get 0.37, or $0.37 per popsicle.
