The bus arrives at our local bus stop at 8am. The other day my brother and I were going to catch the bus and we went to the bus stop at 7:50am so we had to wait for 10 minutes. My 10-year-old brother was too eager to get on the bus. When it was 7:55 am my brother eagerly asked me:
How much more do I have to wait?
(You have to wait) for another five minutes.
Could I have answered it a bit differently by saying:
You have to wait for the same amount of time that you have already waited.
Or should I use for another same amount of time that you have...?
I'm not a native speaker, Please help me.
Thanks in advance.
