You must maintain a pace of 6.91 mph
It depends upon how fast you run. It is a little over three miles. If you are able to average running at about a 9 mph pace for the distance, your time will be about 27 minutes.
6.7 mph
I run 2.5 km run in 12 minutes at about the speed of 15 mph and im 12 years old and today i actually ran a 1/4th a mile in a time of 1min and 27 sec but i play sports like basketball and football and im the fastest kid in my grade but im also very athletic so you should run at an average 10 mph if your really fast but im super fast and i only gave about 75% of my top speed today. ps. hope u liked my answer.
About 27-30MPH
Approximately 27 minutes 30 seconds.
18 miles in 40 minutes equates to 27 mph.
27 divided by 9 = 3 hours
he can't run that fast considuring hes on steroids.
Minutes per mile = 35/3.7 = 9.46 approx * * * * * * 9 minutes 27 seconds per mile
It depends on how fast you are and how experienced you are. Normal person (non-runner): 35-45 minutes Beginning runner: 30-40 minutes Average runner: 28-34 minutes Fast runner: 24-27 minutes Good cross country runner: 20-24 minutes Really awesome: Under 20 minutes World record: Under 13 minutes If you're a really, really talented runner, you might be able to run a 5K in 15-16 minutes after several years of training. Obviously, very few people will get under that or anywhere close to the world record. Generally, if you can do a 5K in around 25 minutes or less, you're considered pretty good.
Speed = (distance) divided by (time for the distance) Your speed would be exactly 27 miles per 20 minutes. In more familiar units . . . 20 minutes = 1/3 hour 27 miles / (1/3 hour) = 81 miles per hour.
5 hours and 27 minutes = 5*60 + 27 = 327 minutes.
