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