1.5 times 2 times 2.5 times 3 times
I gave my students this multiple choice question: A typical height for a mature eastern white pine tree is 100 feet, but in Ontonagon, Michigan, there is an eastern white pine that has reached 150 feet. How many times larger is the pine tree in Michigan than the typical white pine tree?

Only one answer is correct among these 4 choices:
- 1.5 times
- 2 times
- 2.5 times
- 3 times

Could you tell me which one is correct?

1.5 times
