Jane ran 72 m along the ground (distance), but only wound up 52m from where she started (displacement).

Her average speed was 72/6.8 = 10.6 m/minute, but her average velocity was 7.5 m/minute roughly northeast.

Since the magnitude of that average velocity is only about 0.28 mile per hour, I have to guess that poor Jane is on the barby right about now and the dragon is licking his chops. Poor slow Jane.
