Let d be the distance.

Time at 60km/hr = d/60
Time at 55km/hr = d/55

The time at 60km/hr is 10 minutes = 1/6 hour less than at 55km/hr:

Multiply by the least common denominator, 660

ANSWER: The distance is 110km, or 110,000 meters.

CHECK:
110km at 60km/hr = 110/60 = 11/6 hours = 1 hour 50 minutes
110km at 55km/hr = 110/55 = 2 hours
