What time will the woman leave? [br] [originaltext]Woman My plane is at seven,

Woman My plane is at seven, so I’ll have to leave the office around five-thirty. That should give me enough time to get to the airport, don’t you think?
Man Actually, I think you should leave earlier. Rush hour starts at five. The traffic will be really heavy by five-thirty.
Woman Yes, you’re right. Maybe I’d better plan to leave at four.
Man That’s a much better idea. And, look, you’ll need something to read on that long flight. Take these newspapers with you. I’ve already read them.
