Worked out from OpenStax Elementary Algebra 2e, proportional relationships (rate = quantity per unit) and 2 other sources.
The course has more splits than the display limit of 20; raise "Maximum splits shown" to see the rest.
How this is worked out
6 steps
- Distance = 42.195 km (26.2188 miles).
- Elapsed time = 12658.5 s (3:30:58.50).
- Pace = time / distance = 12658.5 / 42.195 = 300 s per km.
- Pace per mile = 300 x 1.609344 = 482.803 s.
- Speed = distance / hours = 42.195 / (12658.5 / 3600) = 12 km/h.
- Split table built at 1 km intervals.
