96 hours
1) Note that there is a proportional relationship between the number of hours in a day and the number of hours in 4 days. So, we can write out the following:
[tex]\begin{gathered} \text{day}------h \\ 1------24 \\ 4------x \\ \\ \frac{1}{4}=\frac{24}{x} \\ x=4\cdot24 \\ x=96h \end{gathered}[/tex]
2) Thus, the answer is equally proportional to the number of 4 days.
