vslo = 11.8 km/h and vfas = 15.0 km/h
Time taken by the faster runner to finish the race is,
t = d/vfas = 8.00/15.0 = 0.533 h
In an 8.00km race, one runner runs at a steady 11.8 km/hr and another runs at 15.0 km/hr. How far from the finish line is the slower runner when the faster runner finishes the race?
