Just divide the distance (26.2 miles) by the time in hours

Robert            26.2 miles / 2.121 hours = 23.372 miles / hour
Margaret        26.2 miles / 2.345 hours = 11.173 miles / hour
Ernst              26.2 miles / 1.305 hours = 20.077 miles / hour
Jean             26.2 miles / 1.523 hours = 11.203 miles / hour
