Question 14 (1 point) A cylindrical water tank is being filled at a constant rate so that the height h(t), in meters, is rising according to the function h (t) = t + 6, in which t is the time in minutes. At the same time, a conical tank is being emptied so that its height g(t), also in meters, is decreasing according to the function g (t) = 12 It + 50 The number of minutes that pass before the two water levels are at the same height, in metres, is
