Person playing games with me and leaving my messages on read?

If you were 17 and you found this job(a job helping someone's 8 year old after school with homework). The mother has said she wants to meet you in 2 days but to text her Monday(yesterday) to confirm. You did that and asked if she is still good to meet with you at 4:30pm on Wednesday? She said Yes. So, you don't own a car and need to plan in advance to see how far away she lives from you(you know what town, but you need her address),to determine when you need to get going. You text her "What is the address, so I can see how early I need to leave in order to get there on time?" She left your message on read. Even though she told you she would give you all the info on Monday(we have had this confirmed for a week) as she is going on a quick business trip Tuesday and won't have good cell phone connection. What would you do? Would you wait a bit and try asking her again? Isn't that rude of her knowing we are supposed to meet tomorrow and she has not answered but has seen my messages?

How much time has passed exactly? One day? I'd suggest wait a little bit more, and try to ask again.. maybe she's just busy and didn't have time to answer.

Yes, I would allow for more time to pass.

I don't immediately reply to texts. I just don't find them the same priority as other methods of communication - like the phone. Unless the situation requires an immediate response I will leave doing so until later. In fact, I don't even check my texts except for maybe once a day to begin with.

If this is something you DO need an immediate response from the more appropriate way to communicate would have been to do so over the phone. If it's not too late, give her a call.
