A 5:00 per km pace is what speed in km/h?

Question

A runner holds a steady pace of 5 minutes per kilometre. Solve in your head. What speed is that in km/h? Aim: under 10 seconds.

Accepted Answer

Pace (minutes per km) and speed (km per hour) are reciprocals over 60 minutes: 	ext{speed} = \frac{60 	ext{ min/h}}{5 	ext{ min/km}} = 12 	ext{ km/h.} Takeaway. To flip pace into speed, divide 60 by the minutes-per-km. Useful anchors: 6:00/km = 10 km/h, 5:00/km = 12 km/h, 4:00/km = 15 km/h. It is the same reciprocal relationship as "time = distance / speed," just with the units rearranged.
