The equation that relates xxx, yyy, zzz, and www is  xxxyyy = wwwzzz

Since Wilmer went up the hill for xxx minutes at a speed of yyy kilometeres per minute, the distance d he moves up the hill is d = speed × time = yyy × xxx = xxxyyy.

Also, Wilmer travels the same path at a speed of zzz kilometers per minute and it took him www minutes. So, the distance d' he moves down hill is d' = speed × time = zzz × www = wwwzzz.
