Distance = 120 km.
Time taken = 6 hours.
Speed of car starting fromA=120/6.
=20 km/hour.
Speed of car starting from B=distance/speed of car starting from A.
=120/20.
=6 km/hour.
The above solution is for same direction.
Time taken = 4320 seconds.
Speed of both the cars= 120000/4320.
=27.77 m/second.
The speed is same because they are in opposite direction.
but it is wrong
no..honey,
