PSLEZane pushes two sticks, Q and R, straight into the ground until the length of each stick that is above the ground is the same.
16 of Q and
110 of R are in the ground. The length of Q in the ground is 24 cm longer than the length of R in the ground. What is the total length of sticks Q and R?
Fraction of Stick Q above ground
= 1 -
16 =
56 Fraction of Stick R above ground
= 1 -
110 =
910 Heights of Sticks Q and R above ground are the same.
56 Q =
910 R
4554 Q =
4550 R
Length of Stick Q more than length of Stick R
= 54 u - 50 u
= 4 u
4 u = 24
1 u = 24 ÷ 4 = 6
Total length of Sticks Q and R
= 54 u + 50 u
= 104 u
= 104 x 6
= 624 cm
Answer(s): 624 cm
