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?
