About 4.61 mph.
1 mile in 4 minutes = 15 miles per hour
You need to run at an average speed of 15 mph.
No ones ever run a mile in 3 mins the lowest has been 4 mins and something seconds, if ur doing a 10 lap that = a mile u'd need need to do about 20 secs a lap.
You need to get your cardiovascular strength up to par, and have the correct nutrition. Along with this, you must train, simply by running.
The minimum speed you need to go to travel 1 mile in 30 minutes is .5 miles per hour, or 44 feet per second. actually to travel one mile in 60 minutes (one mile per hour),you walk...well,one mile per hour.Therefore to walk the same distance in half the time,you have to double the speed,in this case,2 miles per hour.
It depends on how experienced you are as a runner. Beginner: 3 miles or so (11-12 min/mile) Average runner: about 3.5 miles (10 min/mile) Fast: about 4.5 miles (8 min/mile) Experienced XC runner: about 5 miles (7 min/mile) Elite runner/really awesome XC runner: about 6-7 miles (5-6 min/mile) Anything faster than 5 min/mile for 35 minutes is craziness. If you ran more than 7 miles in 35 minutes...you don't need to be asking whether that's a good number of miles :P
To average 8 minutes and 15 seconds per mile, you would need to complete 1.84 miles in 15:10.8 There are 495 seconds in 8:15 (8*60+15)=495 seconds 495 seconds * 1.84 = 910.8 seconds 910.8/60 = 15 minutes with remainder of 10.8 seconds
Assuming you maintain a constant speed throughout your run, you will need to be running the mile at a pace of 8:00 minutes. So, by dividing 60 minutes by your time of 8 minutes you get 7.5. This means you will have to run a pace of 7.5 mph for 12 minutes to travel 1.5 miles.
If you went at a speed of a mile a minute, or 60 mph, you would travel 25 miles in 25 minutes. For 10 miles in this time you only have to travel at 2/5 of that speed, or 24 mph.
Yes, you can. If the average speed for the first mile is 30 mph, and the average speed for the second mile is 90 mph, then 30+90=120/2=60. You need to solve the equation for average speed, not time. You can't. 1 mile @ 30mph = 2 minutes 60 mph for 2 miles = 2 mintes thererfore you cannot go fast enough (or you could go infinity mph)
60 miles per hour !
