Answer:
The rate is
cups per hour
Step-by-step explanation:
It took the faucet 1 1/2 hours, i.e 1.5 or 3/2 hours to fill 1/4 cup by leaking
We need to find the rate in terms of cups that can be filled by water in 1 hour.
Using unitary method:
If it takes
h for
cup;
then it will take 1 h for how many cups?



cups
Therefore, the rate is
cups per hour
93 in base 10 converted into base 4 would 1131
There shouldn't be a negative in front of one of the equations.
