Answer:

Rate = 12345.67 (cubic foot per second)

Flow rate = 49.3826

Step-by-step explanation:

Computation:

7.5 gallons = 1 cubic foot

1 gallon = 1 / 7.5 cubic foot

So,

8 billion gallon = (8 / 7.5) billion cubic foot

Rate = [8/(7.5 × 24123456 × 60 × 60)]

Rate = 12345.67 (cubic foot per second)

Flow rate = (12345.67/25,000) 100

Flow rate = 49.3826

see below

Step-by-step explanation:

Right triangle

cosine 60 =adjacent leg / hypotenuse

      cosine 60 = x / 22      x = 22 cos 60 = 11

sine 60 = opposite side / hypotenuse = y/22

22 sin 60 = y = 22 * sqrt (3) / 2 = 11 sqrt 3    or   19.05
