Answer 2

Water Tank Filling Problem

To solve this problem, we can calculate the time it takes for the tank to be filled by considering the rate at which water is being added and the rate at which it is being drained.

Given: - Tank capacity: 2100 liters - Water added per hour: 400 liters - Water drained per hour: 50 liters

Calculating the Time to Fill the Tank

Let's calculate the net amount of water added to the tank per hour: - Net water added per hour = Water added per hour - Water drained per hour - Net water added per hour = 400 liters - 50 liters - Net water added per hour = 350 liters

Now, we can calculate the time it takes to fill the tank completely: - Time to fill the tank = Tank capacity / Net water added per hour - Time to fill the tank = 2100 liters / 350 liters/hour - Time to fill the tank = 6 hours

Therefore, the tank will be completely filled with water in 6 hours.
