Answer Question
Question 7) One point five hours
In the expression "ban xiaoshi" we present the idea of one and a half hours. But there's no reference to the "one" hour in this. So, if I want to say two and a half hours, how do I achieve this? Further, how do I present "half an hour" since I clearly can't just leave out the one from one-and-a-half (I guess I could say 30 minutes, but that's cheating, and I certainly don't want to refer to one hundred and fifty minutes! :)
