    Answer:

    The time taken for the package to reach the ground is 20.6s

    Explanation:

    Given that the formula of distance is D = S×T where S represents soeed and T is time. So you have to substitute the following values into the formula :

    distance = speed \times time

    let \: distance = 105 \\ let \: speed = 5.10

    105 = 5.1 \times t

    5.1t = 105

    t = 105 \div 5.1

    t = 20.6 \: second \: (3s.f)
