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?
Answers
Divide the total the lake holds by the number of days:
400 million / 25 days = 16 million gallons per day.
The maximum rate of drainage, in millions of gallons per day is 16 millions of gallons per day.
What is a word problem?
A word problem is a verbal description of a problem situation. It consists of few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation.
For the given situation,
Amount of water reservoir can hold = 400400400 million gallons of water ≈ million gallons
Estimated days will drainage take = 252525 days ≈ days
Then the maximum rate of drainage, in millions of gallons per day is
⇒
⇒
Hence we can conclude that the maximum rate of drainage, in millions of gallons per day is 16 millions of gallons per day.
