Question
Two water tanks at a factory begin draining at the same time. The large tank contains
1198
liters of water and drains at a rate of
19
liters each minute. The small tank holds
120
liters of water but is only
5
6
full. It drains at a much slower rate of only
1
liter each minute. How many liters of water are in each tank at the moment that they have the same amount of water?

Let's first find out how long it will take for both tanks to have the same amount of water remaining.
Let x be the number of minutes it takes for both tanks to have the same amount of water remaining.
For the large tank:
Remaining water in large tank = 1198 - 19x
For the small tank:
Remaining water in small tank = 120 * (5/6) - x
Setting the two expressions equal to each other:
1198 - 19x = 120 * (5/6) - x
1198 - 19x = 100 - x
Rearranging:
18x = 1098
x = 61
After 61 minutes, both tanks will have the same amount of water remaining.
Plugging x back into one of the expressions to find out how much water will be left in each tank:
Remaining water in large tank = 1198 - 19*61 = 1198 - 1159 = 39 liters
Remaining water in small tank = 120 * (5/6) - 61 = 100 - 61 = 39 liters
Therefore, after 61 minutes, both tanks will have 39 liters of water remaining.
Let x be the number of minutes it takes for both tanks to have the same amount of water remaining.
For the large tank:
Remaining water in large tank = 1198 - 19x
For the small tank:
Remaining water in small tank = 120 * (5/6) - x
Setting the two expressions equal to each other:
1198 - 19x = 120 * (5/6) - x
1198 - 19x = 100 - x
Rearranging:
18x = 1098
x = 61
After 61 minutes, both tanks will have the same amount of water remaining.
Plugging x back into one of the expressions to find out how much water will be left in each tank:
Remaining water in large tank = 1198 - 19*61 = 1198 - 1159 = 39 liters
Remaining water in small tank = 120 * (5/6) - 61 = 100 - 61 = 39 liters
Therefore, after 61 minutes, both tanks will have 39 liters of water remaining.
