55% of the round-trip

Explanation:

A technician makes a round-trip to and from a certain service center by the same route means 100% of the trip

the technician completes the drive to the center means half of the trip 50%

then completes 10 percent of the drive from the center means 10% of the 50%

so in total he completes

50 + 50*0.10

50 + 5

55 %

Therefore, the technician has completed 55% of the round-trip.
