hello
to solve this question, we need to convert or know the number of cups in a gallon
1 us gallon = 16 us cups
[tex]\begin{gathered} 1\text{ gallon = 16 cups} \\ 24\text{ gallons= x cups} \\ x\text{ = 16}\times24 \\ 24\text{ gallons = 384 cups} \end{gathered}[/tex]
we have 384 cups in 24 gallons
now, this water can be drained in 5 minutes
the rate per second = ?
[tex]\begin{gathered} 1\text{ minute = 60 seconds} \\ 5\text{ minutes = x seconds} \\ \text{x = 5}\times60 \\ x=300s \end{gathered}[/tex]
now, 384 cups were drained in 300s
to find the rate per seconds
384 cups / 300 = 1.28 cups/ sec
