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