A river 3 m deep and 40 m wide is flowing at the rate of 2 km per hour. How much water will fall into the sea in a minute?

Explanation

To solve the problem of how much water will flow into the sea from a river that is 3 m deep, 40 m wide, and flowing at a rate of 2 km per hour, we can follow these steps:

### Step-by-Step Solution:

1. **Convert the flow rate from km/h to m/min**:
- The flow rate is given as 2 km/h.
- To convert kilometers to meters, we multiply by 1000 (since 1 km = 1000 m).
- To convert hours to minutes, we divide by 60 (since 1 hour = 60 minutes).
