Question

I have to make a word problem/story out of this quadratic equation -t^2+3t+18=0 The plot of the story I want to write about has to deal with world hunger, and food being dropped in to remote locations by helicopter. Can someone please help me come up with a word/problem that includes the quadratic equation above? Im a freshman and I don't want to fail this class, but I don't know how to do it by myself. Thank you in advance for your help.
