perhaps they mean the absolute value of displacement/time forexample you can run round a circle the equivalent of five miles in 1 hour or a straight line in the first case the velocity vector changes continously in the second case it will the vector and scalar values would be equivalent...but the absolute value of diplacement/time would still be 5 mph...although funny enough the FARs have no definition for GS
