Answer:

Part-I

Distance = 2465 km

Speed = 920 km/h

Time taken = distance/speed = 2465/920 = 11/4 h

Part-II

Disatnce = 322 km

Speed = 840 km/h

Time taken = 322/840 = 23/60 h

Total distance covered = 2465 + 322 = 2787 km

Total time taken = 11/4 + 23/60 = 188/60 = 47/15 h

Average speed = 2787 x 15/47 = 889.46 km/h
