PSLEGlen pushes two poles, F and G, straight into the ground until the length of each pole that is above the ground is the same.
14 of F and
18 of G are in the ground. The length of F in the ground is 16 cm longer than the length of G in the ground. What is the total length of poles F and G?
Fraction of Pole F above ground
= 1 -
14 =
34 Fraction of Pole G above ground
= 1 -
18 =
78 Heights of Poles F and G above ground are the same.
34 F =
78 G
2128 F =
2124 G
Length of Pole F more than length of Pole G
= 28 u - 24 u
= 4 u
4 u = 16
1 u = 16 ÷ 4 = 4
Total length of Poles F and G
= 28 u + 24 u
= 52 u
= 52 x 4
= 208 cm
Answer(s): 208 cm
