On a 120 km track, a train travels the first 30 km at a uniform speed of 30 km/h. How fast must the train travel the next 90 km so as to average 60 km/h for the entire trip ?

Speed of the train in the first 30 km, v1 = 30 km/h

Speed of the train in the next 90 km, v2 (to be determined)

Average speed = 60 km/h = (v1 + v2)/2
