Answer;

velocity(v) = 97.2 m/s ,

distance (S) = 100 m

determine time(t) = ?

  We know that,

               distance (S) = velocity(v) × time(t)

           So,      time (t) = distance ÷ velocity

                                   = 100 ÷ 97.2

                                t = 1.02 sec.

I hope this will help you.
