After the semester is over, you discover that the math department has changed textbooks (again) so the bookstore won't buy back your nearly-new book. You and your friend Anna decide to get creative. You go to the rook of a five-story building and look over the edge to the reflecting pool 60 feet below. You drop your book over the edge at the same instant that Anna chucks her book straight down at 30 feet per second. By about how many seconds does her book beat yours into the water (approximately)? Your function is s(t)=−16t2+60 Anna's function is s(t)=−16t2−30t+60
