PSLEVaidev pushes two rods, V and W, straight into the ground until the length of each rod that is above the ground is the same.
14 of V and
18 of W are in the ground. The length of V in the ground is 16 cm longer than the length of W in the ground. What is the total length of rods V and W?
Fraction of Rod V above ground
= 1 -
14 =
34 Fraction of Rod W above ground
= 1 -
18 =
78 Heights of Rods V and W above ground are the same.
34 V =
78 W
2128 V =
2124 W
Length of Rod V more than length of Rod W
= 28 u - 24 u
= 4 u
4 u = 16
1 u = 16 ÷ 4 = 4
Total length of Rods V and W
= 28 u + 24 u
= 52 u
= 52 x 4
= 208 cm
Answer(s): 208 cm
