Final answer:
Jamie and Frank spent 33% of their two-hour pool visit playing sand volleyball. This was calculated by subtracting the time they spent on other activities (swimming and water slides) from the total time and then finding the percentage of the remaining time.
Step-by-step explanation:
Jamie and Frank spent two hours at the neighborhood pool. They were busy with activities for different durations: swimming for 45 minutes, playing on the water slides for 35 minutes, and playing sand volleyball for the rest of the time. To find what percent of the time they played sand volleyball, we first need to calculate the total time they spent on the other activities.
- Swimming: 45 minutes
- Water slides: 35 minutes
Next, we add the time spent swimming and on the water slides:
45 minutes + 35 minutes = 80 minutes
Since they were at the pool for two hours, which is equivalent to 120 minutes, we subtract the 80 minutes from 120 minutes to find out how long they played volleyball:
120 minutes - 80 minutes = 40 minutes
Now, to find the percentage of time spent playing sand volleyball, we divide the volleyball time by the total pool time and multiply by 100:
(40 minutes / 120 minutes) × 100 = 33%
Therefore, Jamie and Frank spent 33% of their time playing sand volleyball at the pool.
