The World's Fastest Growing Plant
Bamboo can have an extraordinarily fast growth rate (up to 250 cm per day!).
Unfortunately for Sam, he didn't realize how fast bamboo can grow when he bought a new plant for his living room. He purchased some 50 cm tall bamboo, placed it next to his couch, and then left for a weekend trip.
When he returned 2 days later, his 2.5 m high ceiling was damaged because the bamboo had just started to push through it.
In cm per day, how fast did the bamboo grow?
