Ahmad bought a piece of rope and cut it into 3 pieces. The first piece was 1.3 m longer than the second piece. The third piece was 3.06 m shorter than the first piece.
- If the second piece was 11.61 m, find the length of the rope before it was cut.
- How much did Ahmad pay if each metre of the rope was $10?
(a)
Length of the first piece of rope
= 11.61 + 1.3
= 12.91 m
Length of the third piece of rope
= 12.91 - 3.06
= 9.85 m
Length of the rope
= 11.61 + 12.91 + 9.85
= 34.37 m
(b)
Amount that Ahmad paid
= 34.37 x 10
= $343.70
Answer(s): (a) 34.37 m; (b) $343.70
