initial velocity of the car=40 km/hr
the final velocity of the car = 50km/hr
the initial distance taken by the car=100km
the final distance taken by the car=125km
formula of average velocity= total distance
-----------------
total time
lets put the number
so we will get
100+125
-----------
40 +50
=225
--------
90
=2.5
