Maths anyone??

There is a pole in a lake. One-half of the pole is in the ground, another one-third of it is covered by water, and 8 ft is out of the water. What is the total length of the pole in ft?

[Hari Seldon]

24 feet - or do I need to convert this to metric?

[Father-Time.]

No Wrong answer, and it is ok to put the anser in feet, Metric..??? :oops:

12 ft

48 ft. You guys obviously don't do well with word problems.

1/2 = 3/6
1/3 = 2/6
Total: 5/6

1 - 5/6 = 1/6 = 8 ft.
8*6 = 48 ft.

Yes well done Coby.

To elaborate on the 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 8 ft.
So, total length of pole = 48 ft.

It may be noted that:
Length of pole in the ground = 48/2 = 24 ft.
Length of pole covered by water = 48/3 = 16 ft.
Length of pole out of water = 8 ft.


The problem may also be solved by setting up the following equation: x/2 + x/3 + 8 = x
where x denotes the total length of the pole in ft.
The equation may be solved as shown below.
5x/6 + 8 = x
8 = x - 5x/6 = x/6
x/6 = 8 or x = 48.

Please, give me more math. You're looking at a boy that's minoring (or double majoring if possible) in Applied Math.
