It depends on your weight, height, age, and metabolism. The harder you run, the more calories you will burn! For the most efficient workout, push the limit of how hard you run each time. You will be able to get the best cardio workout that way.
That is about 538 calories burned there.
To run 1 mile in eight and a half minutes you must maintain a speed of 7.06 mph
No, it does not. If only it were so easy.
If it takes 39 minutes to travel 2.7 miles it will take 14 minutes 26 seconds to travel one mile.
The number of minutes in a mile will vary depending on your pace while running or walking. On average, it takes most people around 12-15 minutes to walk a mile, while running a mile typically takes 7-10 minutes.
If you're on a treadmill, walking/jogging at about 3 mph, it will take 40-60 minutes. The less body fat you have, the harder it is to lose it. I'm 140 lbs, and it takes me roughly twenty minutes to walk a mile on a treadmill (with high incline) at 3.2 mph, and for every mile I walk, I burn 100 calories. So it takes me twice as long to burn 200. Taking into account your smaller weight and therefore (probably) smaller fat percentage, it'll take you anywhere up to half a mile more to burn as many calories.
It depends on your weight, but figure around 100 for the average person...
About 20 minutes to walk a mile.
60 minutes = 1 hour 2x60/30 = 4 mph
5 mph is five miles in an hour or 5 miles in 60 minutes. Therefore it takes 60/5 or 12 minutes to travel just one mile.
1 minute 20 seconds.
At 45 mph it takes 1 minute 20 seconds to drive one mile.
