Find the distance for each section of the journey:
60 * 0.52 = 31.2km
30 * 0.24 = 7.2km
70 * 0.71 = 49.7km

The total distance traveled = 31.2 + 7.2 + 49.7 = 88.1km
The total time = 0.52 + 0.24 + 0.71 = 1.47h

The average speed = distance / time = 88.1 / 1.47 = 59.9kmph

Since the values in the question are to 2 signnificant figures I would round the answer to 2 significant figures also. So 60kmph.
