Answer 1

Step-by-step explanation:

Short Answer: 3320 km

Long Answer:

Fact: If the journey is completed in two halves with same time, one at speed x and the other at speed y, then the average speed of the whole journey is (x+y)/2

Here x = 900 and y = 760

Thus average speed for the whole journey is (900+760)/2 = 830 km/h

As total time is 4 hours, the distance traveled is 4 x 830 = 3320 km
