PSLEJack pushes two sticks, N and P, straight into the ground until the length of each stick that is above the ground is the same.
18 of N and
112 of P are in the ground. The length of N in the ground is 32 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 -
18 =
78 Fraction of Stick P above ground
= 1 -
112 =
1112 Heights of Sticks N and P above ground are the same.
78 N =
1112 P
7788 N =
7784 P
Length of Stick N more than length of Stick P
= 88 u - 84 u
= 4 u
4 u = 32
1 u = 32 ÷ 4 = 8
Total length of Sticks N and P
= 88 u + 84 u
= 172 u
= 172 x 8
= 1376 cm
Answer(s): 1376 cm
