When she finished the work, the time was 6:10 p.m. In other words, 6 hours and 10 minutes.
It says that she took 45 minutes to complete the work.
We need to find the time when she started working on it.
Start Time = Finish Time - time taken to complete work.
Start Time = (6 hours and 10 minutes) - 45 minutes
(Hint:- 1 hour = 60 minutes)
Start Time = (5 hours and 70 minutes) - 45 minutes
Start Time = 5 hours and 25 minutes i.e. 5:25 p.m.
It means that she started the work at 5:25 p.m.
