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