Answer:
See the average speed will be average distance divided by time.
But in this case we have not been given time so we assume it 1 hr.
so
average speed = 60 + 80 /2= 140/2 = 7 kmph ;
and we know that average velocity is displacement per unit time and here displacement is 0( since it returns to it original position that is A)
average velocity = 0

oops i made a typo, the average speed will be 70kmph instead of 7 .
