Two trains leave from the same station at the same time, moving in opposite directions. One train averages 95 km/h, and the other train averages 105 km/h. How long after leaving the station will the trains be 400 km apart?
They are parting company at a rate of 95 + 105 = 200 km/hr
400 km / (200 km/hr) =
in TWO hours they will be 400 km apart
hey thats pretty good
