You can put this solution on YOUR website!
First car (car1) speed v%5B1%5D+=+x+%28km%2Fh%29
Second car (car 2) speed v%5B2%5D+=+y%28+km%2Fh%29
second car passes the lad mark 1 hour later:
in one hour car 2 has passes d=+x+km

They are traveling in same direction
to catch up speed: v%5B2%5D-v%5B1%5D=+y-x+%28km%2Fh%29
to catch up distance: d=+x+km
to catch up time t=+%28x+%2F+%28y-x%29%29+h
