PSLECarl pushes two poles, W and X, straight into the ground until the length of each pole that is above the ground is the same.
17 of W and
111 of X are in the ground. The length of W in the ground is 14 cm longer than the length of X in the ground. What is the total length of poles W and X?
Fraction of Pole W above ground
= 1 -
17 =
67 Fraction of Pole X above ground
= 1 -
111 =
1011 Heights of Poles W and X above ground are the same.
67 W =
1011 X
3035 W =
3033 X
Length of Pole W more than length of Pole X
= 35 u - 33 u
= 2 u
2 u = 14
1 u = 14 ÷ 2 = 7
Total length of Poles W and X
= 35 u + 33 u
= 68 u
= 68 x 7
= 476 cm
Answer(s): 476 cm
