Answer:
The average speed is the ratio of total traveled distance to total time taken.
Let d be the total distance traveled by the car.
Thus distance traveled in each journey is d/2.
So, the time taken for going up the hill is t

=
v

(d/2)
=

d/2
=

d
Time taken for going down the hill is t
2
=
66
(d/2)
=
132
d
Thus, average speed is v
