Space traveler moving at a speed

Reference no: EM13664013

A space traveler moving at a speed of 0.62c with respect to the earth makes a trip to a distant star that is stationary relative to the earth. He measures the length of this trip to be 7.9 light-years. What would be the length of this similar trip (in light-years) as measured by a traveler moving at a speed of 0.85c with respect to the earth?
