Her average speed is 1.6 miles per hour. Average speed is total distance covered by total time taken to do it. She swims 4 miles upstream, and at 1 mph, it takes 4 hours. She comes back downstream at 4 mph and so she covers the 4 miles in 1 hour. Her total mileage is 8 miles. It takes 4 + 1 hours or 5 hours to cover it. The 8 miles divided by 5 hours is 1 3/5 miles per hour, or 1.6 mph for an average speed.

The average is 40 mph because if you go up a hill that is 60 miles long, it will take you two hours. And if you travel down 60 mph, it will take you one hour. Divide 120 miles (60 miles going up, 60 miles coming down) by three hours (two hours going up, two hours going down) and you get an average of 40 mph.
It would depend on how fast you're going--if you're going an average of 50 mph, then it would take approximately 26 hours for 1300 miles.
