Sorry guys posted a different answer for pole in water!! OPPS!!
Heres the right one!
Solution:
Fraction of pole in the ground = 1/2
Fraction of pole covered by water = 1/3
Fraction of pole in the ground and covered by water = 1/2 + 1/3 = (3 + 2)/6 = 5/6
Fraction of pole out of water = 1 - 5/6 = 1/6
Thus, one-sixth of the pole (out of water) is 12 ft.
So, total length of pole = 72 ft.
It may be noted that:
Length of pole in the ground = 72/2 = 36 ft.
Length of pole covered by water = 72/3 = 24 ft.
Length of pole out of water = 12 ft.
