The Main Difference Between How Long vs How Much Time
The easiest way to understand How Long vs How Much Time is by focusing on the idea behind the question.
“How long” asks about the duration of an activity.
“How much time” asks about the amount of time available or used.

The first question asks about the total duration of the event.
The second question asks about the time someone personally used.
