The rope was cut into 3 pieces so that the first piece was 3 meters shorter than the second and 3 meters longer than the third piece. How many meters is the third piece shorter than the second.
Let the first piece be x meters, then the second piece of rope will be (x + 3) meters because the first is 3 meters shorter than the second.
The third piece is 3 meters shorter than the first, which means the third piece is equal to (x-3) meters.
Subtract the third piece from the second:
(x + 3) – (x-3) = x + 3-x + 3 = x-x + 3 + 3 = 6
Answer: the third piece is shorter than the second by 6 meters
