PSLEFabian pushes two rods, G and H, straight into the ground until the length of each rod that is above the ground is the same.
16 of G and
19 of H are in the ground. The length of G in the ground is 18 cm longer than the length of H in the ground. What is the total length of rods G and H?
Fraction of Rod G above ground
= 1 -
16 =
56 Fraction of Rod H above ground
= 1 -
19 =
89 Heights of Rods G and H above ground are the same.
56 G =
89 H
4048 G =
4045 H
Length of Rod G more than length of Rod H
= 48 u - 45 u
= 3 u
3 u = 18
1 u = 18 ÷ 3 = 6
Total length of Rods G and H
= 48 u + 45 u
= 93 u
= 93 x 6
= 558 cm
Answer(s): 558 cm
