Although the actual amount varies by season and time of day, the average volume of water that flows over the falls each second

lutik1710 [3]

Given that the average volume of water that flows over the falls each second is $4.8 \times 10^5$ gallons.

There are 3,600 seconds in one hour.

Thus, in one hour, $4.8 \times 10^5\times3600=17280\times10^5=1.728\times10^9$ gallons of water flows over the falls.

Therefore, the amount of water that flows over the falls is $1.728\times10^9$ .
