Answer:

70 km/h

Step-by-step explanation:

Average speed of the car = Total distance covered by car/total time taken.

Total Distance covered = Speed×Time.

= (Speed×Time for the first two hours)+(Speed×Time for the next three hours).

Total Distance covered = (100×2)+(50×3)

Total Distance covered = 200+150=350km.

Total time taken = 3+2 = 5 hours.

Average speed during the trip = 350/5 km/h

Average speed during the trip = 70 km/h.
