The graph shows the amount of water in the pool vs. time relationship for filling a kiddie pool with a small hose and a large hose. Select all of the true statements.

• The amount of water in the pool vs. time relationship for both the large and small hoses are proportional relationships.

• It takes 6 minutes to fill the pool with the large hose and 12 minutes with the small hose.

• The speed as a unit rate for filling the pool with the large hose is 2.5 gallons per minute.

• If the pool is filled with the small hose for 4 minutes it will have 10 gallons of water.

• The relationship between time, t, and the amount of water, w, for the small hose can be represented by the equation w = 2.5t.
