Earth takes 24 hours for one complete rotation on its axis. If rotational speed of Earth is halved then it will complete one rotation in just double time i.e., 48 hrs. Earth completes one revolution in its orbit around Sun in about 365 days. If distance between Earth and Sun is doubled, i.e., radius of Earth's orbit is doubled then it will complete one revolution around Sun in just double time, i.e., 730 days.
