In this case, the skier IRRELEVANT. The formula is simple, the speedboat.
22T - 34 (1 - t) = 0, shows the speed from top to bottom, and the time = 1
22T - 34 + 34t = 0
56t = 34
t = 607 h
, 607 * 22 = 13.36 km upstream of the time 607 h.
(1 -, 607) = 393 h
.393 * 34 = 13.36 miles was the interval 393 h
