To solve this problem we can use the formula:

Time = Distance / Speed

For the first part of the trip, the driver travels 100.0 miles at 60.0 mi/h, so the time taken is:

Time1 = 100.0 miles / 60.0 mi/h = 1.67 hours

For the second part of the trip, the driver travels 50.0 miles at 55.0 mi/h, so the time taken is:

Time2 = 50.0 miles / 55.0 mi/h = 0.91 hours

Therefore, the total time taken for the trip is:

Total Time = Time1 + Time2 = 1.67 hours + 0.91 hours = 2.58 hours

So the best choice is C, which matches the calculated value.
