You can put this solution on YOUR website!
1 hr before, it showed 7:47
2 hrs before, it showed 6:49
3 hrs before, it showed 5:51
. . . . .
30 hrs before, it showed in minutes 8:45 - 30*60 + 30x2 = 8:45 - 1800 + 60
8:45 - 1740 = 8:45 - 29 hrs
8:45 - 24 hrs = 8:45
8:45 - 5 hrs = 3:45
The answer is E)
