Answer: The Millers need 15 gallons of water for 6 minutes.
Lets start by finding how much water is needed for 1 min shower.
25 gallons of water is used for 10 min shower:
10 mins = 25 gallons
To find 1 min shower, we will divide the 25 gallons of water by 10.
10 mins = 25 gallons ← Divide by 10 on both sides
÷ 10 ÷ 10
1 min = 2.5 gallons
Now that we know the Millers need 2.5 gallons for every 1 minute of shower, we can find 6 minutes of shower by multiplying by 6.
1 min = 2.5 gallons ← Multiply 6 on both sides
x6 x6
6 min = 15 gallons
