Flow rate of 1,600,000 cubic feet per second to cubic feet per week
Hint: Find how many seconds we have in 1 week
60 seconds = 1 minute
60 minutes = 1 hour
24 hours = 1 day
7 days = 1 week
in 1 week, we have (60 x 60 x 24 x 7 )= 604800 seconds
The flow rate per week = 1, 600, 000 x 604,800 = 967,680,000,000 cubic feet per week
The answer is D
