Question

The caterpillar is trying to crawl up the tree. It takes 2 minutes to climb 1 foot, but it falls back 6 inches each time it reaches 1 foot. How long will it take the caterpillar to crawl to the top of the 8 foot tree?

Answer 1

Alright so, judging from this question, we could do some simple algebra. Where x is the height where the caterpillar is in feet, a simple expression would be 2x - 0.5x or x (2-0.5) which is x * 1.5  .just plug 8 in x and you will get the answer.
