Dana's dance practice was over at 6: 15. she had practiced for 1 and a half hours. at what time did her practice begin

No it started at 4:45 because an hour before 6:15 is 5:15 subtract the half hour with his 30 minutes so split in in to 15 and 15 so subtract 15 get 5:00 subtract another 15 from 5:00 and get 4:45

I’m not positive but i think it’s none of your buisness
