a tub takes 4 minutes to fill and holds 28 gallons of water. At this rate, how long would it take to fill a bathtub that held 63 gallons of water?
rate=28/4=7gal/min
time=63/7= 9 min
To answer this question, we need to find the time it takes to fill a bathtub that holds 63 gallons of water, based on the given information that a tub that holds 28 gallons takes 4 minutes to fill.
We can use a proportion to solve this problem. Let's set up the proportion based on the information given:
(28 gallons) / (4 minutes) = (63 gallons) / (x minutes)
To find the value of x, we can cross-multiply:
28 * x = 63 * 4
Now, we can solve for x by dividing both sides of the equation by 28:
x = (63 * 4) / 28
x = 9
Therefore, it would take 9 minutes to fill a bathtub that holds 63 gallons of water at a rate of 4 minutes to fill 28 gallons.
