PSLERael pushes two poles, L and M, straight into the ground until the length of each pole that is above the ground is the same.
18 of L and
111 of M are in the ground. The length of L in the ground is 24 cm longer than the length of M in the ground. What is the total length of poles L and M?
Fraction of Pole L above ground
= 1 -
18 =
78 Fraction of Pole M above ground
= 1 -
111 =
1011 Heights of Poles L and M above ground are the same.
78 L =
1011 M
7080 L =
7077 M
Length of Pole L more than length of Pole M
= 80 u - 77 u
= 3 u
3 u = 24
1 u = 24 ÷ 3 = 8
Total length of Poles L and M
= 80 u + 77 u
= 157 u
= 157 x 8
= 1256 cm
Answer(s): 1256 cm
