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