Divide your total time by the distance. Running 5 km in 30 minutes is 6 minutes per kilometer, which converts to about 9 minutes 39 seconds per mile. A free running pace calculator solves for any of pace, time or distance when you enter the other two, entirely in your browser.
Free running pace calculator. Enter any two of distance, time and pace and it solves the third, for miles or kilometers, with a finish time projection.

Open Running Pace to Speed Converter →Pace, time and distance lock together: pace = time / distance, time = pace x distance, distance = time / pace. That means the same calculator answers three different questions: what pace did I run, what finish time does my pace predict, and how far can I go in a set time. The fiddly part is the minutes and seconds arithmetic, which is exactly what the tool handles.
A mile is 1.609 kilometers, so multiply a per-kilometer pace by 1.609 to get the per-mile figure: 6:00 per km is about 9:39 per mile. To convert pace into speed, divide 60 by the pace in minutes, so 10 minutes per mile is 6 miles per hour. A pace to speed converter does both directions if you prefer treadmill numbers.
Exactly 6:00 per kilometer, or about 9:39 per mile.
Divide 60 by the pace in minutes per mile. A 10:00 mile pace is 6.0 mph.
It extrapolates your pace over a distance. Real races add fatigue, so treat long extrapolations as optimistic.
