Answer:
0.85 c
Explanation:
When the two travel at right angles to each other , their relative velocity is given by the hypotenuse formed by the x and y direction velocities.
Relative velocity of the two protons is  given as
 
If v = 3/5 c , then the relative speed =  (3/5c) =0.85 c
 (3/5c) =0.85 c
