A 20-0 litre bucket can be filled with water using a water hose 3-00 cm in diameter in 2 minutes. Calculate the speed with which the water leaves the hose.

Explanation

To solve the problem of calculating the speed at which water leaves the hose, we can follow these steps:

### Step 1: Convert the volume of water to cubic meters
We know that 1 liter is equal to \(10^{-3}\) cubic meters. Therefore, we can convert 20 liters to cubic meters:
\[ \text{Volume} = 20 \, \text{liters} = 20 \times 10^{-3} \, \text{m}^3 = 0.020 \, \text{m}^3 \]
