from 8:02 to noon is 3 hours and 58 minutes

from noon to 4:27 is 4 hours and 27 minutes

that's a total of 7 hours and 85 minutes.

take away 3/4 of an hour means taking away 45 minutes.

you are left with 7 hours and 40 minutes.

40 minutes is the same as 40/60 = 2/3 of an hour.

2/3 of an hour is roughly .66666667 of an hour.

7 + .66666667 of an hour is 7.6666667 of an hour which is closer to 7.65 of an hour than any of the other selections.

Your answer is selection D.
