Clock A runs 1 minute fast per hour. Clock B runs 7 minutes slow per day. If the clocks show the same time at noon, how many minutes ahead of clock B will clock A be 48 hours later?

The answer is 34 but I forgot how I got the answer. I remember getting -33. 5 so I guessed 34. Can anyone help me out?

Answer:

So after 360 hrs, clock A and B both will show the same time. Clock A will show the correct time, whereas clock B will be running faster by 12 hrs and therefore show the same time, though different in AM and PM. A clock which advances 12 hours will appear to show the same time again. 12hours*60minutes/hour=720 minutes.
