To find out how many hours it will take to fill the pool, we can use the formula:

$\text{Time} = \frac{\text{Pool Capacity}}{\text{Rate of Water Flow}}$

Where:

• Pool capacity = $3.5 \times 10^4$ gallons = 35,000 gallons
• Rate of water flow = 630 gallons per hour

Now we calculate the time:

$\text{Time} = \frac{35,000 \text{ gallons}}{630 \text{ gallons per hour}} = 55.56 \text{ hours}$

Rounding to the nearest whole number:
