Question 10
Mouse, Cat and Rat start in the positions shown. Mouse always moves 1 cell to the left per jump; Rat always moves 1 cell to the right. Cat may jump 2 or 3 cells either left or right. If Cat decides to catch Mouse first, what is the fewest jumps needed to catch both rodents? All three always jump simultaneously. (The labels “Chuột Nhắt” and “Chuột Cống” mean “Mouse” and “Rat”.)
