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.
To run a half mile in 4 minutes and 13 seconds, you would need to maintain a pace of around 8 minutes and 26 seconds per mile. This is considered a moderately fast pace for most runners.
5.625 (= 55/8) miles per hour.
1 and a half. There are one and a half minutes in one and a half minutes.
60 minutes equals an hour and half an hour is 30 minutes so 60 min+30 min =90 minutes.
