Question

h(t)=80+64t -16t. How do I solve for time

Answer 1

Do you know the quadratic formula?

Answer 2

Simplify by combining similar terms getting h(t) = 48t + 80 Now use algebra:
48t = h(t)-80
t = (h(t)-80)/48
Obviously you need to know the value of h(t) to solve for t.

Answer 3

Okay, that helped a whole lot. Thank you so much :)
