Answer:

Average speed for the trip is 912.75 km/hr

Explanation:

Total time of the first leg of the trip:
2100 km / 1000 km/hr = 2.1 hrs

Total time of the second leg of the trip:
1300 km / 800 km/hr = 1.625 hrs

Total time of the trip:
2.1 hrs + 1.625 hrs = 3.725 hrs

Total distance traveled on both legs of the trip:
2100 km + 1300 KM = 3400 KM

Average speed of this trip:
3400 km / 3.725 hrs = 912.75 km/hr
