PSLEZane pushes two sticks, D and E, straight into the ground until the length of each stick that is above the ground is the same.
14 of D and
18 of E are in the ground. The length of D in the ground is 16 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 -
14 =
34 Fraction of Stick E above ground
= 1 -
18 =
78 Heights of Sticks D and E above ground are the same.
34 D =
78 E
2128 D =
2124 E
Length of Stick D more than length of Stick E
= 28 u - 24 u
= 4 u
4 u = 16
1 u = 16 ÷ 4 = 4
Total length of Sticks D and E
= 28 u + 24 u
= 52 u
= 52 x 4
= 208 cm
Answer(s): 208 cm
