Let’s Begin…
As a wildfire rages through the grasslands, three lions and three wildebeest flee for their lives. To escape the inferno, they must cross over to the left bank of a crocodile-infested river. Can you help them figure out how to get across on the one raft available without losing any lives? Lisa Winer shows how.
Suppose the raft can hold 3 animals. What is the maximum number of wildebeest and lions that will be able to cross?
