Q: A river flows through a region with a soil erosion rate of 5 tons per hectare per year. If the area of the watershed is 100 hectares, how much soil is eroded in a year?

Solution: Soil eroded = Erosion rate × Area = 5 tons/hectare/year × 100 hectares = 500 tons/year.

Steps: 5

Step 1: Identify the erosion rate, which is given as 5 tons per hectare per year.
Step 2: Identify the area of the watershed, which is given as 100 hectares.
Step 3: To find the total soil eroded, multiply the erosion rate by the area: 5 tons/hectare/year × 100 hectares.
Step 4: Calculate the result: 5 × 100 = 500 tons.
Step 5: Conclude that the total soil eroded in a year is 500 tons.
