This is a simple formula based one.
Average speed = total distance/ total time
Total distance = 8+6+16 = 30 km
Total time taken = 3 quarters of an hour = ¾ hr
Average speed = total distance/ total time = 30/(3/4) = 40 kmph
Average speed = total distance/ total time
Total distance = 8+6+16 = 30 km
Total time taken = 3 quarters of an hour = ¾ hr
Average speed = total distance/ total time = 30/(3/4) = 40 kmph

Calculation of Average Speed:
- To calculate the average speed of the car over the entire journey, we need to first determine the total distance covered by the car and the total time taken.
Total Distance Covered:
- The car travels 8 km in the first quarter, 6 km in the second quarter, and 16 km in the third quarter.
- Therefore, the total distance covered is 8 km + 6 km + 16 km = 30 km.
Total Time Taken:
- The car travels 8 km in the first quarter of an hour, 6 km in the second quarter, and 16 km in the third quarter.
- Therefore, the total time taken is 1/4 hour + 1/4 hour + 1/4 hour = 3/4 hour.
Calculation of Average Speed:
- Average speed = Total distance / Total time
- Average speed = 30 km / (3/4) hour
- Average speed = 30 km / 0.75 hour
- Average speed = 40 km/hour
Therefore, the average speed of the car over the entire journey is 40 km/hour. Hence, the correct answer is option 'C'.
