First car 40 mph
Car II 90 mph
First car 09:00
Car II 10:00
Difference in time= 01:00 => 1.00 hours
First car will have covered 40.00 miles Car II starts
catch up distance= 40.00 miles
catch up speed = 90 -40
catch up speed = 50 mph
Catchup time = catchup distance/catch up speed
catch up time= 0.8
catch up time= 0.80 hours =48 minutes
