36/4 would find the average number of pages she read per hour. since you are dividing the total number by the number of hours she took in total.
HOWEVER, bare in mind that this is not always an accurate representation of how many pages she DID read, since she might have read some pages slower than others.
BUT you can generalise and say she read 9 pages (36/4) every hour, on average <span />

Well you are given the equation so let's plug in for kaylib and see how many miles she can see
distance = sqrt [(3 * height) / 2]
d = sqrt [(3 *48) / 2]
d = sqrt (144 / 2)
d = sqrt (72)
d = sqrt (3 * 3 * 2 * 2 * 2)
d = 6 * sqrt (2)

You you did not list Addisons height but I will say she is at x feet above sea level. we plug in x for height:
d = sqrt [(3x) / 2]

It it says how much farther for Addison which means she can see farther. to find difference we just subtract kaylibs distance from Addison. so:
sqrt [(3x) / 2] - 6 * sqrt (2)

plug in your x and use a calculator to get a decimal approximation
