We cannot entertain multiple question of this type, please post each question individually and let us know where you are getting stuck so that we would be able to explain things better.

Take upward direction as positive and downward direction as negative. Find time taken to reach highest point which means that v =0. use u = 200m/s a = -9.8m/s2 then using v=u+at solve for t

double the value of t to find the total time.
