Sure, let's do this step by step:
1. First, we need to identify what we are trying to find. We are looking for the rate of coverage, which means how much area is covered per unit of time.
2. We know the total area covered is 650 square feet.
3. We also know the time it took to cover that area is 2/3 of an hour.
4. To find the rate of coverage, we divide the total area by the total time taken.
5. So we do 650 (the total area) divided by 2/3 (the total time).
6. The result of this calculation is 975.
7. Therefore, the rate of coverage in this scenario is.
Answer: 975 square feet per hour
