Susie walks 240 m at an average speed of 1,5 m.s ] across a bridge from point A to point B and then jogs for 100 m from B to meet Thandi at the jetty at point C. It takes Susie a total time of 3 minutes to get from point A to the jetty at point C. Pythag 2 2 = 21102 +16oz 2 : 567600 Diagram is not to scale.
