Answer 1

Hey 2nd one is more faster by 5km/s as speed of 1st car is 120/3 =40 km/s and of 2nd car is 180/4=45km/s.

Answer 2

Distance= 180 km


Time = 4 hrs
Speed =distance /time


=180/4
=45 km/hr

Now other train

Distance= 120 km
Time=3 hrs
Speed = distance/time

=120/3
=40 km/hr


Therefore first train is faster
