Answer: 2/15
Step-by-step explanation:
25-21/30 = 4/30
4/30 = 2/15
San 13/15, John 69%, Phillip 12/18. When you divide 13/15 you'll get 86. When you divide 12/18 you'll get 66.

Marcel leaves 30 minutes after Carolyn, leaving between them a gap of 40mph*0.5h=20miles
To catch up with the 20miles, Marcel uses the extra (65-40=25)mph that he has.
Therefore 20m/25mph=0.8h=0.8*60min=48minutes after 2:45, which is at 3:33, Marcel catches up to Carolyn.
