5-51.

Four pieces of rope of unknown (but equal) length and 10 more feet of rope are attached together. The resulting rope is 30 feet long. Homework Help ✎

Draw a diagram to represent this problem.

First, draw the 4 pieces of rope of unknown and equal length.

Then draw the 10 foot rope.

Find a way to indicate that the whole rope is 30 feet long.

How long is each of the pieces of rope that is not 10 feet? Show how you know.

The four unknown lengths combine to be 20 feet, so how long must each length be?
