Two runners start simultaneously from the same point on a circular $200-m$ track and $\mathrm{run}$ in opposite directions. One runs at a constant speed of 6.20 $\mathrm{m} / \mathrm{s}$ , and the other runs at a constant speed of 5.50 $\mathrm{m} / \mathrm{s}$ . When they first mect, (a) for how long a time will they have been running, and (b) how far will each one have run along the track?

Step 1
Since they are running in opposite directions, we can add their speeds to find the relative speed. The relative speed is $6.20 \, \mathrm{m/s} + 5.50 \, \mathrm{m/s} = 11.70 \, \mathrm{m/s}$. Show more…

Two runners start simultaneously from the same point on a circular 200-m track and run in the same direction. One runs at a constant speed of 6.20 m/s and the other runs at a constant speed of 5.50 m/s. Part A When will the faster one first overtake (lap) the slower one? Part B How far from the starting point will each have run at that instant?
