Respuesta :

Answer:

Option (C).

Explanation:

It is given that,

The rate at which waterfalls at the Niagara Falls is about 84,760 ft³/s. We need to find how many liters of waterfall in a period of exactly 1 hour.

Since, 1 feet³ = 28.3168 L

1 hour = 3600 seconds

So,

[tex]84760\ \dfrac{ft^3}{s}=84760\times \dfrac{28.3168\ L}{(\dfrac{1}{3600\ s})}\\\\=8.6405\times 10^9\ L[/tex]

Hence, the correct option is (C).
