i think the average speed was 54.54 (mph)
AL2006

Average speed  =  (distance covered)  /  (time to cover the distance)

                             =    (300 miles)            /        (5.5 hours)

                             =      ( 300 / 5.5 )  miles/hour

                             =          54.55 mph
