To find the average speed, we need to calculate the total distance traveled and the total time taken.
Total distance = 60 km (first two hours) + 68 km (next two hours) = 128 km
Total time = 2 hours (first two hours) + 2 hours (next two hours) = 4 hours
Average speed = Total distance / Total time
Average speed = 128 km / 4 hours
Average speed = 32 km/h
So, the car's average speed is 32 km/h. The correct answer is c) 32 km/h.
Total distance = 60 km (first two hours) + 68 km (next two hours) = 128 km
Total time = 2 hours (first two hours) + 2 hours (next two hours) = 4 hours
Average speed = Total distance / Total time
Average speed = 128 km / 4 hours
Average speed = 32 km/h
So, the car's average speed is 32 km/h. The correct answer is c) 32 km/h.
