Homework Statement
[/B]
Chris runs round a track at a speed of 6 km/hour. Dave runs round the same track in a speed of 9 km/hour. When Chris has run 18 laps, how many laps has Dave run?
2. The attempt at a solution
Dave runs 1.5 times faster. So Dave will run 18 laps x 1.5 = 27 laps in the same time.
Is this correct please?
