Answer:

6 m/s

Explanation:

Recall that average velocity is the quantity final position minus initial position, divided by the time it took. So in our case, the cheetah after all the away and back and away again, the mother got a total of: 30 - 10 + 40 = 60 m

and the total time is: 2 + 3 + 1 + 4 = 10 second

Then the average velocity is: 60 m / 10 sec = 6 m/s
