Answer:
Average speed= total distance/total time
Total distance= 60+50=110
Total time= 4+3=7

Answer:
54.28km/hr
Explanation:
In 1st Case~
Distance covered by car in 1 hr=60kms.
therefore distance in 3 hours=3×60=180kms.
In 2nd Case~
Distance covered by car in 1 hr=50kms
therefore distance in 4 hrs=4×50=200kms
Thus,
Total distance covered by car=180+200=380kms
Total time taken= 3+4= 7 hrs
Now,
Average Speed of the car=
Average Speed of the car=Total distance covered/total time taken
=380/7
=54.28km/hr
HENCE THE AVERAGE SPEED OF THE CAR IS 54.28 km/hr
