Car speed 100 mph
Police car speed 120 mph
Difference in time= 15 minutes = 1/4 hour
Car will have covered 25 miles befor police car starts
catch up distance= 25 miles
catch up speed = 120 -100 mph
catch up speed = 20 mph

Catchup time = catchup distance/catch up speed
catch up time= 25 / 20
catch up time= 1.25 hours
