Thirty minutes after the vehicle passed the CMD, he observed that a COVID-19 infected dog is running in the same direction as the vehicle.
(I) with a suitable diagram, using Galilean transformation, show the coordinates of the CMD as measured by the COVID-19 infected dog.
(II) if the medical volunteer is 1500km from the dog, what is the coordinates of the dog as determined by the CMD?
