Travel periods are 18 hours each period.

Let u be the conversion factor from kilometers to miles, as u%28km%2Fmile%29.

RT=D
T=D%2FR

20000%2Akm%2A%281%2F45%29%28hour%2Fmiles%29%2A%281%2Fu%29%28mile%2Fkm%29, but this is total time IN HOURS. Now you have 1 day = 18 hours as a conversion ratio also.

%2820000%2F%2845u%29%29%281%2F18%29, the number of days if travel period is 18 hours per day.
