Motorboat speed 9 mph
cabin cruiser 18 mph
Difference in time=> 2 hours
Motorboat will have covered miles before cabin cruiser starts
catch up distance= 18 miles
catch up speed = 18 -9 mph
catch up speed = 9 mph
Catchup time = catchup distance/catch up speed
catch up time= 18 / 9
catch up time= 2 hours
