Practice and training. The record for a mile is less than 4 minutes, so half a mile should be easy.
5.625 (= 55/8) miles per hour.
It works out as 15 miles per hour. Pace aside, four minutes is an extremely fast time for a mile. Anybody who runs that fast should drop whatever they are doing regerdless of priority and start their Olympic training. A 4 minute mile was prviously thought humanly impossible.
Very.
1 mile in 8 minutes = 7.5 miles in 60 minutes ie 7.5 mph
It matters how much you want to run.

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.
I think if you are a fast runner I think you should sprint half and jog half your last mile.

8 minutes
8-10 minutes, probably.
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.
from 2 and half minutes to 3 minutes.
Faster
At 71 I walk a mile 14 min 17 sec and run a mile 11min 55 sec.
