Hi Carmi, The track has a circumference of 110 meters and when they are both at the start position, facing in opposite directions, the distance between them is 110 meters. After they start to run Lita is at position $L$ in my diagram and Rose is at position $R.$ How fast is the distance between them decreasing? How long will it take for the distance between them to decease from 110 to 0 meters? Penny |
