A tree casts a 25 foot shadow. At the same time of day, a 6 foot man standing near the tree casts a 9 foot shadow. What is the approximate height of the tree to the nearest foot?

Cross multiply this proportion and solve for x.

x/25 = 6/9
37.5 feet
I think that the answer is 37.5 but, only because of what I am thinking in my head not, because of something that one of you said...
Your ratios are off. Plugin 37.5 into the answer. Why would a tall tree cast a shorter shadow? If anything the shadow should be longer not shorter. We know the tree is shorter than 25 feet.
