they are going 279 miles at a rate of 62 mph.

time = distance / speed
time = 279/62
time = 4.5 hrs...or (4 hrs 30 minutes)

plus they plan on a 45 minute lunch...
4 hrs and 30 minutes + 45 minutes = 4 hrs and 75 minutes = 
5 hrs 15 minutes. So they need 5 hrs and 15 minutes to get there...and they want to be there by 3.

So they will have to leave at : 9:45 <==
