Room for another problem?
Clement and Victor were out for a cycling trip. Clement ran into a tree, damaging his bicycle. They were 16 km from home. They decided that Clement would walk first and Victor would cycle. After sometime, Victor would leave his bicycle on the road and continue walking home, so that Clement would reach the bicycle and continue to cycle home. Clement walked at 4km/h and cycled at 10 km/h, while Victor walked at 5 km/h and cycled at 12 km/h. For what length of time should Victor cycle if they were both to arrive home at the same time?
