QUESTION $1$

The table below shows two hours near the maximum of the design hyetograph based on the NRCS Type II rainfall distribution. What is the depth of rainfall for a $24\mathrm{.}0-$minute design storm based on these data?

$\backslash$table$[[\backslash$table$[[$Time$],[($hr$)]],P($in$),\backslash$table$[[$Time$],[($hr$)]],P($in$),\backslash$table$[[$Time$],[($hr$)]],P($in$)],[11\mathrm{.}0,1\mathrm{.}27,11\mathrm{.}7,1\mathrm{.}91,12\mathrm{.}4,3\mathrm{.}91],[11\mathrm{.}1,1\mathrm{.}31,11\mathrm{.}8,2\mathrm{.}32,12\mathrm{.}5,3\mathrm{.}96],[11\mathrm{.}2,1\mathrm{.}35,11\mathrm{.}9,3\mathrm{.}06,12\mathrm{.}6,4\mathrm{.}01],[11\mathrm{.}3,1\mathrm{.}41,12\mathrm{.}0,3\mathrm{.}57,12\mathrm{.}7,4\mathrm{.}05],[11\mathrm{.}4,1\mathrm{.}46,12\mathrm{.}1,3\mathrm{.}68,12\mathrm{.}8,4\mathrm{.}09],[11\mathrm{.}5,1\mathrm{.}53,12\mathrm{.}2,3\mathrm{.}77,12\mathrm{.}9,4\mathrm{.}13],[11\mathrm{.}6,1\mathrm{.}65,12\mathrm{.}3,3\mathrm{.}84,13\mathrm{.}0,4\mathrm{.}16]]$

QUESTION $2$

Using the data from Question $1,$ what is the average rainfall intensity for the $24\mathrm{.}0-$minute period producing the most runoff?
