30 feet.
Split into 1/4 feet segments of rope.
We can convert 30 to inches and then divide by 3:
12/4=3 (that is a quarter of a foot)
12*30= 360
360/3= 120
There are 120 pieces of quarter foot rope.
You could also say for every 1 foot, there are 4 quarters.
30*4= 120 <== same answer
I hope this helps!
