Answer: 11 hours and 25 minutes
Step-by-step explanation:
Since she left at 7:10 am you can add 50 minutes and you will get 8, then all the way to 6 pm is 10 hours. Now you just have 50 and 35 minutes that you havent added to the total yet so when you add those two together you get 85. But there isnt 85 minutes in a hour so you would have yo break it down and you would get 1 hour and 25 minutes. Add 1 hour and 25 minutes to 10 hours and you get 11 hours and 25 minute. I hope that helps!
