Between 8:30 and 6:30 is 10 hours. That is 600 minutes which is 36000 seconds. So you would do 600•2= 1200 and then do 36000-1200=34800 seconds. 34800/60=580 minutes so you would then take 540/60=9 which would make the time 5:30 p.m. but there is 40 minutes left over so it would end up being 6:10 p.m. lol I hope this is right because it took me forever
