Show the working
- Distance = 10
- Time, hours = 0
- Minutes = 52
- Seconds = 30
- Total time = 0*3600 + 52*60 + 30 = 3150
- distance_km = 10 = 10
- Pace per kilometre = 10 > 0 ? 3150 / 10 : 0 = 315
- Pace per mile = 315 * 1.609344 = 506.943
- Speed = 315 > 0 ? 3600 / 315 : 0 = 11.4286
- Speed in miles per hour = 11.4286 / 1.609344 = 7.101 39
- Pace per 400 m = 315 * 0.4 = 126
- Distance in miles = 10 / 1.609344 = 6.213 71
Values are shown to six significant figures here; the arithmetic itself runs on exact fractions and is only rounded where a number is printed.
