Runner A is initially 5.0 km west of a flagpole and is running with a constant velocity of 4.6 km/h due east. Runner B is initially 8.8 km east of the flagpole and is running with a constant velocity of 7.0 km/h due west. What will be the distance of the two runners from the flagpole when their paths cross?

Question

Convert units to m/s.
$$5_{km}=5000_m$$
$$8.8_{km}=8800_m$$
$$\frac{ 4.6 }{ 3.6 } = 1.277_{m/s}$$
$$\frac{ 7 }{ 3.6 }=1.944_{m/s}$$
