so we know one bag can do 1/7 of all students, how many will it be needed to do 7/7?
well, in 7/7 there are seven 7/7, so, 7 bags then, or one could say,
From the right triangle formed, the adjacent side to the angle of elevation is 5 miles and the vertical change in elevation is the opposite side. From the trigonometric function, tangent of an angle,
tan 12° = x / 5 miles
The value of x from the equation is 1.06 miles. Thus, the vertical change in elevation is 1.06 miles.
If n is an even integer:
n(n + 2) = 48
n^2 + 2n - 48 = 0
(n + 8)(n - 6) = 0
n = -8 or n = 6
2 miles per minute. Dang, that's one fast guy.
