Schlagwörter Pythagoras, Time

Find the total time for a journey taken by a group of walkers.

The object is to get a group of people from the starting point ‘Start’ to the finishing point ‘Finish in the shortest possible time. The speeds you can walk at on the low (flat) ground and high ground are different. A stream marks the boundary between the two walking surfaces and students are required to use Pythagoras and s/d/t calculations to find the shortest total time for the journey.
