I travel at .9c for 1 second. From a stationary frame of reference, only 0.316 seconds has passed for me. So from there frame of reference, I traveled 269813212 meters in only 0.316 seconds or 2.8c or 280% the speed of light. :surprised I know that you cannot literally travel faster than light itself, because these same effects would apply to light itself or anything else traveling near c, I just wanted to point this out. I typed this quickly so if there are any mathematical errors in it please tell me and I will edit it.
