Jada walks up to a tank of water that can hold up to 10 gallons. When it is active, a drain empties water from the tank at a constant rate. When Jada first sees the tank, it contains 7 gallons of water. Three minutes later, the tank contains 5 gallons of water.
2. How many more minutes will it take for the tank to drain completely? Explain or show your reasoning.
Since the tank can hold up to 10 gallons and there are currently 5 gallons left, that means 5 gallons have been drained from the tank.
Using the information provided, we can calculate that the rate at which the water drains is 5 gallons in 3 minutes. So, the rate of draining is 5/3 = 1.67 gallons per minute.
To find out how many more minutes it will take for the tank to drain completely, we can divide the remaining 5 gallons by the draining rate of 1.67 gallons per minute.
Therefore, it will take approximately 3 more minutes for the tank to completely drain.
