Questions & Step-by-Step Solutions
A river has a width of 300 meters and a depth of 5 meters. What is the volume of water flowing through the river in one second if the flow speed is 2 m/s? (2020)
Step 1: Identify the width of the river, which is 300 meters.
Step 2: Identify the depth of the river, which is 5 meters.
Step 3: Identify the flow speed of the water, which is 2 meters per second.
Step 4: Use the formula for volume: Volume = Width × Depth × Speed.
Step 5: Substitute the values into the formula: Volume = 300 m × 5 m × 2 m/s.
Step 6: Calculate the volume: 300 × 5 = 1500, then 1500 × 2 = 3000.
Step 7: The final answer is that the volume of water flowing through the river in one second is 3000 cubic meters.
Volume Calculation – The volume of water flowing through a river can be calculated using the formula Volume = Width × Depth × Flow Speed.
Units of Measurement – Understanding the units involved (meters for width and depth, meters per second for speed) is crucial for accurate calculations.
