A 120-metre-long rope is cut into 3 pieces. The first piece of rope is twice as long as the second piece of rope. The third piece of rope is three times as long as the second piece of rope. What is the length of the longest piece of rope?

1st rope- 2x
2nd rope- x
3rd rope- 3x
2x+x+3x=120
6x=120
x=20
3rd rope-3x
x=20
20x3=60
The longest and third rope is 60m long.
