Since the pick is suggesting your allowing super forms.
SSJ Trunks at his best has been calc'd at mach 280-600, Super Silver in his fight with Solaris was dodging the same attacks as Super Sonic and Super Shadow were so he should be around their speed, so most likely LightSpeed to FTL. Silver would most likely use his PK to stop Trunks from moving and prob throw him somewhere, ideally 太空 where he can't breathe.
