Question

Start time unknown elapsed time 9 3/4 hours end time 6 pm

Answer 1

9 3/4 hrs = 9 hrs 45 minutes
end time = 6 pm
beginning time = 8: 15 am

Answer 2

The start time is 9:15 A.M. I believe.

I took away 6 hours from the elapsed time to get 12:00 P.M. (noon). Then, I took away another 3 hours to get 9:00 A.M. Now, we only have 3/4 hour left. 3/4 of 60 is 45. 60 - 45 = 15. Add 15 minutes to 9:00.

Hope it helps,
