that runner will run at 13 MPH
It depends on how fit you are and how fast you can run: in my case, probably 5 hours!
It is impossible to run that fast, but if it were, it would take 2 hours.
The marathon runner is running at 26 miles per 2.5 hours (26 miles / 2.5 hours), or 10.4 miles per hour.
While they may not look it, gorillas can run very fast if they want to. A gorilla can run at up to twenty miles an hour.
26.2 miles in 3.6 hours = 7.27 miles per hour (about an 8.25 minute mile)
Your average speed is 6.67 mph
You would have to maintain an average speed of 6.2 miles per hour.
Seven minutes is 7/60 hours. If you want to make your speed in miles per hours then divide 7 into 60. 60/7=about 8.57 miles per hour. A fast jogger could do this. I'm a fast walker and can average 4.1 mph.
To cover 26 miles in 4.25 hours, you need to run at approximately 6.11764706 mph, but for general purposes 6.12 miles per hour should be close enough.
You must maintain a pace of at least 6.55 miles per hour for 13.1 miles.
as fast as you want them to run
