Arunner is jogging in a straight line at a
steady vr= 2.1 km/hr. when the runner is
l= 4.4 km from the finish line, a bird begins
flying straight from the runner to the finish
line at vb= 10.5 km/hr (5 times as fast as
the runner). when the bird reaches the finish
line, it turns around and flies directly back to
the runner.
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.
i've been having so much trouble it isn't even funny

Adiver named jacques observes a bubble of air rising from the bottom of a lake (where the absolute pressure is 3.50 atm) to the surface (where the pressure is 1.00 atm). the temperature at the bottom is 4.00 ∘c, and the temperature at the surface is 23.0 ∘c.what is the ratio of the volume of the bubble as it reaches the surface (vs) to its volume at the bottom (vb)? if jaques were to hold his breath the air in his lungs would be kept at a constant temperature. would it be safe for jacques to hold his breath while ascending from the bottom of the lake to the surface?
