It matters how much you want to run.
If your goal is a 11 min. mile and a half, your mile time should be about 7:33.
Three and half miles per 23 minutes. ;)
thirteen and a half = 13.5
2 minutes and a half per km
7.5 mph
If you are half a year older than thirteen then you are mostly thirteen and a half. Thogh not legally.
half a second if you walk fast
Take the distance in miles (1.5) and divide by the time in hours. Since 12 minutes is .2 hours, you would divide 1.5 by .2 to get 7.5 mph.
The pace to run a half mile in 4 minutes 13 seconds is 7.12 (7.11462451) miles per hour.
5.625 (= 55/8) miles per hour.
1 and a half. There are one and a half minutes in one and a half minutes.
A space station goes very fast. It orbits the earth every 90 minutes! (hour and a half)
