Question

Mike uses 120 pints of water to take a 5 minute shower. Dad uses 100 quarts for a 10 minute shower. Maria uses 24.8 gallons for an 8 minute shower. Who uses the most gallons of water per minute? Explain.

Answer 1

Then Maria uses 3,1 gallons /min is the user with most gallons of water per minute

Explanation:

Mike uses 120 pints of water for a 5 minutes shower

1 gallon is equal to 8 pints therefore Mike uses 120/8 gallons for a 5 minutes shower

W(mi) = 120 / 8 gallons

W(mi) = 15 gallons for a 5 minutes shower

Dad uses 100 quarts, as a gallon is equal to 4 quarts

W(d) = 100 / 4

W(d) = 25 gallons for a 10 minutes shower

And Maria

W(ma) = 24,8 gallons for an 8 minutes shower

Then:

Mike uses 15 gallons / 5 min

Mike uses 3 gallons / min

Dad uses 25 gallons / 10 minutes

Dad uses 2,5 gallons / min

Maria uses 24,8 gallons / 8 min

Maria uses 3,1 gallons /min

Then Maria uses 3,1 gallons /min is the user with most gallons of water per minute
