Question

Although the actual amount varies by season and time of​ day, the average volume of water that flows over the falls each second is 4.84.8 times ×10 Superscript 5105 gallons. How much water flows over the falls in an​ hour? Write the result in scientific notation.​ (Hint: 1 hour equals 3600​ seconds)

Answer 1

Given that the average volume of water that flows over the falls each second is
`4.8 * 10^5` gallons.

There are 3,600 seconds in one hour.

Thus, in one hour,
`4.8 * 10^5*3600=17280*10^5=1.728*10^9` gallons of water flows over the falls.

Therefore, the amount of water that flows over the falls is
`1.728*10^9`.
