Average speed  = 

                 (total distance covered) / (time to cover the distance).

Total distance covered = (58km + 80km) =  138 km

Time to cover the distance = (4hr + 4hr) =  8 hours

Average speed  =  138km / 8hr  =  17.25 km/hour .

(That's less than 11 mph.  You could bike there faster!)
