Question

Every minute, 2 gallons of water flows from a shower. A family of 5 people showers for an average of 9 minutes per person every morning. How many gallons of water does the family use for showering every morning?

Answer 1

90 Gallons

Explanation:

So to start we know that

a. every 1 min = 2 gallons

b. 5 ppl shower for 9 minutes each (on average)

so we can solve we multiplying amt. of ppl showering and the mins. they shower which is 5 and 9 respectively => and we get 45 minutes taken.

We know that each minute equals 2 gallons so we simply multiply 45 and 2 = 90 => and thus, we have our answer of 90 gallons.

Hope this helps!

Answer 2

90 gallons

Explanation:

5 people at 9 minutes each = 45 minutes
