Model 2: Alternate Days and Cycles

04 Try it yourself Interactive

Cycle by cycle, then the tail

Pick the two solo times and who takes day one. The console finds the cycle work, counts whole cycles, then walks the final part-cycle day by day so you can see exactly where the fraction comes from. Switch who starts and watch the answer move while the cycle count stays put.

A in 16, B in 12, A starts

cycle 7 of 48 · 13.75 days

The closing line compares against the same pair working together every day. An alternating answer should be roughly double it.
