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 5.25.2 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

The amount of water flowing each second is:

rate = 5.2 x 10^5 gallons / second

Since we know that:

1 hour = 3600 seconds

Therefore:

rate = (5.2 x 10^5 gallons / second) * (3600 seconds / hour)

rate = 1.872 x 10^9 gallons / hour
