Question 904072: runner a is initially 6 km west of a flagpole and is running with a constant velocity of 9 km/h due east. runner b is initially 5 km east of the flagpole and is running with a constant velocity of 8 km/h due west. how far are the runners from the flag pole when their paths cross? Answer by richwmiller(17219) (Show Source):
You can put this solution on YOUR website! d=r*t+R*t
11=9*t+8*t
11=17*t
t=0.64705882 hours
d=R*t
d=8*0.64705882
d=5.17647059 miles at 8 mph
5.17647059-5 = 0.17647059 west of pole
d=r*t
d=9*0.64705882
d=5.82352941 miles at 9 mph
6-5.82352941 =0.17647059 west of pole
