From information given, we know

208 miles was at rate of 65 mph. so divide total mileage by speed to get time spent.

208 : 65 = 3.2 hours

So the rest of the trip took 6 - 3.2 = 2.8hours to travel another 348 total miles minus the 208 miles driven at 65mph is 140 miles.

140 miles divided by 2.8 hours gives speed

140 : 2.8 = 50 miles per hour
