Experienced hikers average a greater speed than that even if you average it over 24 hours, so including sleeping time. Someone who can only walk 15km (that’s slightly more than averaging 1.5km/h for 9 hours) a day would never go on a journey like that, and even if they did, they’d be much faster after a few weeks. So there’s no situation where that calculation makes sense.
My estimate wasn’t great, but I’m also thinking about mountain hikes with gear covering large elevation changes in respect to my quoted speed. I guess the varied terrain would averaging things out.
