MATH!!

posted by .

In algebra right now, we're doing inverses and stuff. And I'm not sure if this problem can be solved with using an inverse formular, or just solved regularly....

Brian is rowing in a marathon. When rowing downstream, he is traveling at a rate of 10 miles per hour. While he rests, he travels downstream at a rate of 3 miles per hour. He rows for an hour and rests for an hour.

A. If he continues this pattern, how many hors will it take him to travel 182 miles?

B. What is his average speed per hour?

I really appreciate a little help, or a lot of help. Anything you know about this, help me out!! THANK YOUUU!!

    Since Brian travels 13 miles in two hours, he averages 6.5 miles per hour. Divide 182 by 6.5 to find how many hours it will take him.

    We'll be glad to check your work.
