A runner and a walker begin on a track (oval shape) 1 mile in length at the same spot and depart in opposite directions. The runner goes steadily at 9 mph while the walker goes at a steady 3 mph. How long before they meet again? Show your work!
Let the distance covered by the slower walker be x, then clearly the distance covered by the faster walker would be 1x.
Now the time taken by the slower walker is x/3 and the time taken by the faster walker would be ......??
What do you know about the times taken by each??
Can you take it from here?
hint: 1/12 hour which would be 5 minutes.
