Your brother pulls his sled up a hill. Each minute he moves forward 20 feet, but he also slides backward 3 feet. Describe how you can determine the time he needs to pull his sled 130 feet forward.

Answer 3

First, if you have a question, it is much better to put it in as a separate post in <Post a New Question> rather than attaching it to a previous question, where it is more likely to be overlooked.

Second, state in detail the specific problem(s) that is/are giving you trouble.

I hope this helps. Thanks for asking.
