$\boxed{HERE\:IS\:YOUR\:ANSWER}$

$\mathfrak{\green{ANSWER:}}$

Total distance covered by the car (in km)
= 2400km - 2000 km
= 400 km 

Total time taken taken by the car (in hrs) = 8 hrs

Average speed = Total distance covered/ total time taken 

= 400km/8hr

=50 km/hr

Total distance covered by the car (in m) = 400000m

Time taken (in s) = 28800 sec

Average speed = 400000/28800

= 13.89 m/s
