rate * time = distance is the general formula to use.
60 kilometers per hour * .52 hours = 31.2 kilometers
30 kilometers per hour * .24 hours = 7.2 kilometers
70 kilometers per hour * .71 hours = 49.7 kilometers
total kilometers = 88.1
total hours = 1.47
total average kilometers per hour = 88.1 kilometers / 1.47 hours = 59.93197279 kilometers per hour.
