A 9.6 m rope is cut into pieces of 0.4 m each. From each 0.4 m piece, a knot uses up 0.1 m, leaving the rest as usable length. What is the total usable length (in metres) from all the pieces?

Question

Accepted Answer

7.2 m. Pieces = 9.6 / 0.4 = 24. Usable per piece = 0.4 - 0.1 = 0.3 m. Total = 24 x 0.3 = 7.2 m.
