    Given:

    h=215t-16t^2

    the rocket's height is 97 feet.

    Substituting the value of h.

    97 = 215 t-16 t^2

    Rearranging,

    -16 t^2 - 97 + 215 t = 0

    or

    16 t^2 - 215 t + 97 = 0

    Solving the equation using quadratic formula:

    We get two values of t.

    t = 12.97

    t = 0.46
