Math Problem Statement
005 (part 1 of 2) 10.0 points A runner is jogging in a straight line at a steady vr= 6.2 km/hr. When the runner is L= 5.7 km from the finish line, a bird begins flying straight from the runner to the finish line at vb= 24.8 km/hr (4 times as fast as the runner). When the bird reaches the finish line, it turns around and flies directly back to the runner. L vb vr finish line What cumulative distance does the bird travel? Even though the bird is a dodo, assume that it occupies only one point in space (a “zero” length bird), travels in a straight line, and that it can turn without loss of speed. Answer in units of km
