Question

Tom cut a red rope into 5 equal pieces
that were 9 m long and had 12 m leftover.

rope, what was the length of the blue
rope?
m (enter your answer as a decimal to
the tenth place)​

Answer 1

Answer:

28.5m

Step-by-step explanation:

The red rope is cut into 5 equal pieces with the length 9m and 12m left over

The length of 5 equal pieces are (9×5)m = 45m

12m left over ⇒ Total length is [45+12]m 57m

The length of the red rope is twice of length of the blue rope i.e.,

57 = 2 × length of the blue rope

57/2 = length of the blue rope

∴The length of the blue rope = 28.5m
