Jessica and matthew are running toward the point p along the straight paths that make a fixed angle of θ. suppose that matthew runs with velocity va meters per second and jessica with velocity vb meters per second. assume that θ = π/3. use the chain rule to determine the rate at which the distance f between matthew and jessica is changing when x = 40, y = 30, va = 4 m/s, and vb = 3 m/s.
