Justin bought a piece of rope and cut it into 3 pieces. The second piece was 1.2 m longer than the third piece. The first piece was 2.72 m shorter than the second piece.
- If the third piece was 11.92 m, find the length of the rope before it was cut.
- How much did Justin pay if each metre of the rope was $5?
(a)
Length of the second piece of rope
= 11.92 + 1.2
= 13.12 m
Length of the first piece of rope
= 13.12 - 2.72
= 10.4 m
Length of the rope
= 11.92 + 13.12 + 10.4
= 35.44 m
(b)
Amount that Justin paid
= 35.44 x 5
= $177.20
Answer(s): (a) 35.44 m; (b) $177.20
