Imagine you are in an alternate universe where planets move much faster than normal. To entertain yourself, you set up a camera to point toward Mars and create a time-lapse photo of the planet which moves in real time.
Using the image below, figure out how many seconds it takes for alternate-universe Mars to make a complete rotation.
