    yes, time of ascend is equal to time of descent. And the reason is, acceleration due to gravity is same for both cases. Also in ascending case, final velocity is zero. And in descending case initial velocity is zero. that's why the condition is equivalent

    time of ascent is equal to time of descent only when there is no resistive force... so alwys not equal... I attached a page where time of ascent is equal to time of descent (means mas is thrown upward in a gravity)...
