The table shows the weekly change in the water level in a swimming pool. after 4 weeks, the pool owner adds water to return the water level back to the original level. raising the water level by 1 inch requires 320 gallons. the water hose has a flow rate of 5.75 gallons of water per minute. will it take less than an hour to fill the pool back to return the water level to the original level? explain your reasoning.
week: 1 2 3 4
change (in.): - 1/2 3/4 -1 1/8 -1 3/8
the original question does not mention anything about the water levels.
