i dint undestand 2nd example of adjective of quantity i.e " I don't have much time to answer this question"?????????

I don't have much time to answer this question. Here, 'much' is an example of adjective of quantity. It cannot be an adjective of number as we cannot measure or count time. Therefore, 'much' signifies a non-specific period of time. Hope this explanation helped you understand the concept better.
