Question

The Silver Lake Reservoir in California is being drained to make way for an underwater pipeline. The reservoir holds 400400400 million gallons of water, and it is estimated that the drainage will take at least 252525 days. If the water is drained at a constant rate, what is the maximum rate of drainage, in millions of gallons per day?

Answer 1

Divide the total the lake holds by the number of days:

400 million / 25 days = 16 million gallons per day.
