Assuming the question is asking for your speed in miles per hour (MPH) if you run 8 miles in 2 & 1/2 hours, divide miles by hours: 8 miles divided by 2 & 1/2 hours = 8 miles/2.5 hours = 8/2.5 MPH = 16/5 MPH = 3.2 MPH

Average speed was 65 mph. 100 miles + 420 miles = 520 miles 2 hours + 6 hours = 8 hours 520/8 = 65 mph
8 hours 13 minutes.

5 hours 8 minutes at 60 mph
well, if you go 8 mph (miles per hour) for five hours you can multiply 8 times 5 which is 40. So you would go approximately 40 miles.
5 hours 8 minutes at 60 mph
About 5 hours 8 minutes.
About 8 hours 5 minutes at 65 mph
8 hours.
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.
