Question

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.
How long is each of the pieces of rope that is not 10 feet?

Answer 1

Answer:

5 feet each

Step-by-step explanation:

So we know that 4 pieces of rope out of 5 are equal. So, we simply subtract 10 from 30 for that 10-foot piece of rope, which leaves us with 20. Divide 20 by 4 (since there is 4 pieces of rope of equal value) and it leaves us with 5 feet.
