Assuming the hot air balloon is high enough so that it won't hit the floor during the descent. We know that every minute the balloon is descending 320 feet right? So in two minutes it will descend 320+320=640 feet. And in 3 minutes it will descend 320+320+320 = 960 feet. So the balloon has descended 960 feet in 3 minutes!

Another (faster/better) way of doing this is using the formula $$distance = {speed \times time}$$ In our case speed = 320 and time  = 3.$$320 \times 3 = 960$$
