    Answer: y = 40 + 21t

    Explanation:

    Apply the equation of distance covered.

    d = vt + C

    Where d is the distance covered

    v = velocity, t = time

    C = constant = initial distance covered

    For the case above ...

    d = y

    y (t) = vt + C

    But y (0) = 40 = C

    C = 40ft

    velocity v = 21 ft/s

    Therefore, the equation of the altitude is given by;

    y (t) = 21t + 40

    y = 40 + 21t
