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