A.
9.3005 x 106 L

B.
8.6405 x 1015 L

C.
8.6405 x 109 L

D.
1.4401 x 108 L

Answer 1

Option (C).

Step-by-step 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,

`84760\ (ft^3)/(s)=84760* (28.3168\ L)/(((1)/(3600\ s)))\\\\=8.6405* 10^9\ L`

Hence, the correct option is (C).
