Lap Times The Problem: Two friends are training at
the same running track. In order not to look as if they are directly competing
against each other, they run round the track in opposite directions. Chris normally takes 60
seconds to run a complete lap, but finds that when he and Sophie are running in
opposite directions, they cross each other every 24 seconds. How long is Sophie
taking for each lap? They then decide to
run in the same direction, and set off together. How long will it be before one of them �laps� the other? Open the File as a Word Document
