A running tap dispenses 0.15 gallons of water every second. How many pints of water is dispensed after 20 seconds? Show your work. (1 gallon = 4 quarts, 1 quart = 2 pints)


STEP BY STEP:

1. Take .15 gallons x the total # of seconds to figure out how many total gallons is dispensed. (You should get 3 gallons)

2. Next multiply 3 gallons by 4 quarts to get the total # of quarts per gallon. (You should get 12 quarts)

3. Lastly multiply the 12 quarts by 2 pints to get the total number of pints per 20 seconds. (You should get 24 pints)

((ANSWER: 24 pints per 20 seconds))

.15 gal
X 20 sec
—————-
3 gallons (per 20 sec)


3 gal
X 4 qts
—————
12 qts (per 20 sec)


12 qts
X 2 pts
—————-
24 pints (per 20 sec)
