  1. 28 min=28/60 of a hour
    33 sec=33/3600 of an hour.

    add these to 3hr.

    avg speed=42200m/timeabove

  2. Runner A is initially 2.4 km west of a flagpole and is running with a constant velocity of 7.2 km/h due east. Runner B is initially 8.6 km east of the flagpole and is running with a constant velocity of 7.6 km/h due west. What will be the distance of the two runners from the flagpole when their paths cross?
