Answer 3

Calculating the Time for the Tank to Empty

To calculate the time it takes for the tank to empty, we can use the information provided.

The tank has a capacity of 2100 liters and is being filled at a rate of 230 liters per hour. Additionally, there is a leak causing 300 liters to be lost every hour.

To find out how long it will take for the tank to empty, we can use the following formula:

Time to empty = Initial volume / (Inflow rate - Outflow rate)

Using the given values: - Initial volume: 2100 liters - Inflow rate: 230 liters per hour - Outflow rate: 300 liters per hour

We can calculate the time it will take for the tank to empty using the formula.

Calculation

Time to empty = 2100 / (230 - 300)

Time to empty = 2100 / (-70)

Time to empty = -30 hours

The negative result indicates that the tank will never completely empty under these conditions. This is likely due to the outflow rate being greater than the inflow rate, causing the tank to never reach a point of being completely empty.

Therefore, the tank will never be completely empty under the given conditions.
