You can put this solution on YOUR website!
rabbit 45 mph
Panther 54 mph
Difference in time=00:12= 0.2 hours
Rabbit will have covered 9miles before Panther starts

catch up distance= 9 miles
catch up speed = 54 -45 mph
catch up speed = 9 mph

Catchup time = catchup distance/catch up speed
catch up time= 9 / 9
catch up time= 1 hour
