To determine the time it will take for the diver to reach the water below, we derive the equation such that t will be our unknown and that will be,
                                              t  = √(d/4.9)
Substituting the known values,
                                             t = √(70 m / 4.9) = 3.78 s
Therefore, it will take the diver approximately 3.78 seconds to reach the water below.
