Ответ:      243 км. 358 км.  284 км.

Пошаговое объяснение:

За 3 дня --------- 885 км

За 1 и 2 день ------------- 601 км

За 2 и 3 день ------------ 642 км

***************

Сложим (1 и 2 день) + (2 и 3 день) = 601 + 642 = 1243 км.

За 1 день и 2*2 дня + 3 день = 1243 км;

За (1 день +2 день+3 день) + 2 день = 1243 км

***************

За 2 день =>  1243 - 885 = 358 км

За 1 день => 601 - 358 = 243 км

За 3 день => 642 - 358 =  284 км

****************

Проверим верность решения

243 + 358 + 284 = 885 км !!!

Исё верно!!!
