in a particular inertial frame S, two events occur a distance of 1.0 km apart with event 1 occuring 2.0us before event 2. An observer who is travelling at speed v relative to S in a direction parallel to the line joining the events notes that he events are simuntaneous. Detemine the speed in units of c
