Question 649934: Okay, so I have a word problem that I have to write an equation for. Then I have to write a paper walking another classmate through how to do the problem. I've come up with an equation, but it doesn't fit the standard model for linear equations, which worries me.
Here's the word problem:
In order to build a house, a 15,300 gallon lake must be drained. Water can be drained from the lake at a
rate of 35 gallons per minute.
So I identified my variables,
water - independent variable - g - gallons
time - dependent variable - m - minutes
After staring at it for forever, I could only think that the problem is easily solved by dividing 15,300 by 35.
So my equation is:
m= 15,300/35
Which would make the horizontal intercept 437.14, meaning the lake could be drained completely in 437.14 minutes.
IT SEEMS WAY TOO SIMPLE! Am I doing this problem right?

===================
Volume = flow rate * time
time = Vol/flow
---------------
15300 gallons/35 gal/min = 437.14 minutes
That's all there is to it.
