20 minutes is 20 minutes, and since there are 60 minutes in an hour and we have two hours, we have 60*2=60+60=120 and 120+30=150 minutes spent playing board games, so we have 150+20=170 minutes so far. I challenge you to figure out how many minutes are in half an hour and to add the rest up - good luck, and feel free to ask any further questions!
