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