345.48 x 1.6093 = 555.98 km/h
555.98 / 60 = 9 4/15 km/minute
9 4/15 / 60 = 0.154 km/second
0.154 x 1000 = 154 m/s

Convert to km/hour:
345.48 miles/hour x 1.6093 km/mi = 555.981 km/hour
Convert to m/hour:
555.981 km/hour x 1000 m/km = 555,981 m/hr
Convert to m/s:
555,981 m/hr / 60 minutes/hr / 60 seconds/min = 154.44 m/s
