Step-by-step explanation:
I assume you're asking about it's orbit around the sun. I believe the Earth's orbit around the sun would be shorter. If the Earth sped up, one can assume that means the days are shorter and the rate at which the Earth orbits the sun would also speed up.
This sounds like an open ended question, so I don't think there can be a wrong answer.
Hope this helps! :)
