PSLEHoward pushes two sticks, J and K, straight into the ground until the length of each stick that is above the ground is the same.
17 of J and
111 of K are in the ground. The length of J in the ground is 14 cm longer than the length of K in the ground. What is the total length of sticks J and K?
Fraction of Stick J above ground
= 1 -
17 =
67 Fraction of Stick K above ground
= 1 -
111 =
1011 Heights of Sticks J and K above ground are the same.
67 J =
1011 K
3035 J =
3033 K
Length of Stick J more than length of Stick K
= 35 u - 33 u
= 2 u
2 u = 14
1 u = 14 ÷ 2 = 7
Total length of Sticks J and K
= 35 u + 33 u
= 68 u
= 68 x 7
= 476 cm
Answer(s): 476 cm
