A black squirrel takes minutes to climb a tree. A brown squirrel takes minutes to do the same. Which squirrel climbs the tree faster and by how much?

ABlack squirrel, mins
BBlack squirrel, mins
CBrown squirrel, mins
DBrown squirrel, mins


There is an error in the solution. If we compare 55/20 (distance covered by the black squirrel) and 28/20 (distance covered by the brown squirrel), then obviously 55/20 is greater. (the distance covered by the black squirrel). But in the solution, it is said that the brown squirrel has traveled more distance. Which is actually wrong. I request SOF Olympiad Trainer to correct it.
