A faucet drips 2\3 gallons of water in 10 hours. what is the unit rate of water dripped per day
son4ous [18]

Answer:

unit rate of water dripped per day is \dfrac{8}{5} or  1.6 gallons.

Step-by-step explanation:

We fist have to ask ourselves how many 10 hours are in a day— the answer is

number\:of\:10\:hours\:in\:a\:day=\dfrac{24\:hours}{day} *\dfrac{1}{10\:hours} =\dfrac{12}{5} =2.4

there are  \dfrac{12}{5} or 2.4 sets of 10-hours in day.

Now the unit rate of water dripped per day is

\dfrac{2/3\:gallons}{10\:hours}*\dfrac{12}{5}  = \dfrac{8}{5} =1.6\:gallons/day

unit rate of water dripped per day is \dfrac{8}{5} or  1.6 gallons.
