Step-by-step explanation:
Given,
d=60km
Let's consider the total time taken to cover the distance is t.
If half of the total time traveled with speed 80km/h,
d
1
=80×
2
t
=40t
Rest half time is covered with speed 40km/h,
d
2
=40×
2
t
=20t
The average speed of the car is Total distance covered by the car divided total time,
v
avg
=
t
d
1
+d
2
v
avg
=
t
40t+20t
=
t
60t
v
avg
=60km/h
The correct option is A.
