Simple Harmonic Motion - Physics Unit 4 NEED HELP!

I need help on this question, http://prntscr.com/b3zhnm
I do not know how to do this, I thought of using the phase difference formula which is, phase diff = (2*pi*change in time period)/T
So by substituting the following into the equation:
(2*Pi*0.10)/2 = Pi/10 Radians
From there on I'm unsure? I'd appreciate any help, and explaining how you got there, thanks in advance!
