how many hours to travel 182 miles? average speed?

[jenxowns]

but i'm not sure if it deals with inverses or not...

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 formula, 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!!

How much does he travel in 2 hours - 1 hr rowing and 1 hr rest?

How many of these "2 hour" units would he need to travel 182 miles?

B. What is his average speed per hour?

What is the definition of average speed?
