Runner A is initially 4.0 mi west of a flagpole and is running of 6.0 mi/h due east. Runner B is initially 3.0 mi east of the flagpole and is running with constant velocity of 5.0 mi/h due west. how far are the runners from the flag pole when they meet.??

First, find when they are going to meet and then figure out the location. The distance between the two is 7 miles. The relative speed between the two is 11 mi/h. So the time they meet is 7/11 (h) after they started. Pick either one to find their location. For runner A, the location is 4-6x7/11 miles west of the flag pole.
