It varies throughout the years. At certain points throughout the year, it's literally over 150 million miles closer to Earth than at other times, so it's hard to get an exact distance. It's generally compared to Mars though, which is why I used that measurement, and the speed of light from Earth to Mars is about 182 seconds. So if the PPGs reached it in about 3 seconds, it would put their speed around 60x the speed of light. They're likely a little faster than that though as they didn't move forward in time when they flew to the asteroid belt, but it was likely still around 60x speed of light.
