Speed & pace

Distance: 10 km
Time: 0 h 45 min 0 s (2,700 s)
Kilometers per Hour: 13.33 km/h
Miles per Hour: 8.28 mph
Meters per Second: 3.7 m/s
Pace: 4:30 /km · 7:15 /mile
Time per 100 m: 0:27

Worked solution

11. Convert time to seconds0×3600 + 45×60 + 0 = 2,700 s
22. Normalize distance10 km = 10 km
33. Divide distance by time10 km ÷ 0.75 h = 13.33 km/h
44. Convert units13.33 ÷ 1.609344 = 8.28 mph · 13.33 ÷ 3.6 = 3.7 m/s

Formula

speed = distance ÷ time · km/h → mph: ÷ 1.609344 · km/h → m/s: ÷ 3.6 · pace = time ÷ distance

Pro tips

• 1 m/s = 3.6 km/h — a handy rule for wind and treadmill speeds.
• Pace is the reciprocal of speed: a 12 km/h runner runs 5:00 per km.
