PSLEJack pushes two poles, E and F, straight into the ground until the length of each pole that is above the ground is the same.
18 of E and
112 of F are in the ground. The length of E in the ground is 32 cm longer than the length of F in the ground. What is the total length of poles E and F?
Fraction of Pole E above ground
= 1 -
18 =
78 Fraction of Pole F above ground
= 1 -
112 =
1112 Heights of Poles E and F above ground are the same.
78 E =
1112 F
7788 E =
7784 F
Length of Pole E more than length of Pole F
= 88 u - 84 u
= 4 u
4 u = 32
1 u = 32 ÷ 4 = 8
Total length of Poles E and F
= 88 u + 84 u
= 172 u
= 172 x 8
= 1376 cm
Answer(s): 1376 cm
