A water delivery truck is filling the water tank at Morgan's house. The truck arrived with 2400 L of water. The number of liters

Luda [366]

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

$L = 2400L

$

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:

$L = -110L + 2400L$

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.

$2,400 - 1,100= 1,300

$

Now we can take that number and divide it by how many liters per minute were lost.

$1,300/110=11.81$

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. $L=-110t + 2400, t=11.8$ min

Hope this helps! : )
