Answer:
11.81 minutes
Step-by-step explanation:
Here is a simple step-by-step explaination of how to solve this word problem:
Since the truck has 2,400L in it to begin with, the first part of our equation will be 2,400L
[tex]L = 2400L
[/tex]
Next we know that the water in the truck decreases at a rate of 110L/min, or Liters per minute.
So we will put that in the equation:
[tex]L = -110L + 2400L[/tex]
Now that we have our equation set up, its time to solve.
To figure out how much water it needs to lose in total to end up with 1100 L left, we subtract 1,100 from 2,400.
[tex]2,400 - 1,100= 1,300
[/tex]
Now we can take that number and divide it by how many liters per minute were lost.
[tex]1,300/110=11.81[/tex]
So the total amount of time it took for the truck to have 1,100 L left is 11.81 minutes. Your answer would be
B. [tex] L=-110t + 2400, t=11.8[/tex] min
Hope this helps! : )
