An 18-year-old runner can complete a 10.0 km course with an average speed of 4.57 m/s. A 50-year-old runnercan cover the same distance with an average speed of 4.42 m/s. How much later (in seconds) should the younger runner start in order to finish the the course at the sametime as the older runner?
