A runner is jogging at a steady 3.4 km/hr.
When the runner is 8.8 km from the finish
line, a bird begins flying from the runner to
the finish line at 17 km/hr (5 times as fast
as the runner). When the bird reaches the
finish line, it turns around and flies back to
the runner,
finish
line
How far does the bird travel? Even though
the bird is a dodo, assume that it occupies
only one point in space (a "zero" length bird)
and that it can turn without loss of speed.
