Morning Mental Exercise

You are driving down the highway at the speed limit of 70 mph when another car passes you.  You know that the mile markers alongside the highway are each 1/20th of a mile apart and it takes the other car 6 seconds to get a mile marker ahead of you.  How fast is the other car travelling?

 

I do this one in my head on longer drives to keep my brain active.

  1. Where:
    Tv = target velocity
    Mf = Mile factor
    Tc = Time count
    PvS = Pace vehicle speed
    Tv = (60/Mf((Tc X 20)/60))+PvS

    Therefore,
    Tv = (60/((6*20)/60))+70
    Tv = (60/((120)/60))+70
    Tv = (60/2)+70
    Tv = 30+70
    Tv = 100
