Question
1) In a marathon race (42.195 km), the winner's time is 2 hours, 18 minutes, and 35 seconds, while the second-place time is 2 hours, 24 minutes, and 49 seconds.
Assuming the each runner ran the race at constant speeds, how far (in km) is the second-place finisher behind the first-place finisher as the first-place finisher crosses the finish line?
2) A runner competes in a 10000 m on a 400 m track and crosses the finish line after completing the race. What is the runner's displacement in meters?
