We are given this situation to model using a differential equation: Snow is falling at a constant rate of 3/5 in per hour and is being removed at a constant rate of 45% of the amount of snow on the ground per hour. Removal of snow began at 4 in. If we let h(t) be the height of the snow at time t, then the rate of change of the height of snow would be equal to 3/5 - 0.45h. My question is, why doesn't time appear in the differential equation? Our equation, dh/dt = 3/5 - 0.45h is autonomous, but why?
