    Are you trying to ask about relative speed? To get the relative speed of two objects moving toward each other you add the two speeds. If they are both moving in the same direction, you subtract to get the relative speed.

    Warning! Warning! Pet peeve alert!
    Time X rate = distance
    This isn't your fault, but I hate this one. Rate of what?? Better to say
    "time x speed = distance." Okay, pet peeve over!
