How much longer意思

"How much longer" is an English phrase that is used to ask for an amount of time that is additional to a period that has already elapsed or is currently ongoing. It is often used in situations where you want to know how much more time something will take, or how much longer a particular situation is going to continue.

For example, if you've been waiting in line for 20 minutes and you're curious about how much longer you'll have to wait, you might ask, "How much longer is this line going to take?"

In this context, "how much" refers to an amount, and "longer" indicates that you're asking for an extension of time beyond what has already passed.
