The highest-energy cosmic ray ever detected had an energy

The highest-energy cosmic ray ever detected had an energy of about 3.0x10^20 eV. Assume that this cosmic ray was a proton.

a) What was the proton's speed as a fraction of c?

If this proton started at the same time and place as a photon traveling at the speed of light, how far behind the photon would it be after traveling for 1 year?
