A car travels 100 kilometers in 8 hours and the remaining 40 kilometers in 2 hours. Find the average speed of the journey.

To find the average speed of the journey, we first need to calculate the total distance traveled and the total time taken.

Total distance = 100 km + 40 km = 140 km
Total time = 8 hours + 2 hours = 10 hours

Average speed = Total distance / Total time
Average speed = 140 km / 10 hours
Average speed = 14 km/h

Therefore, the average speed of the journey is 14 kilometers per hour.

Average speed = Total distance travelled / Total time taken
Total distance travelled = 100 km + 40 km = 140 km
Total time taken = 8 hours + 2 hours = 10 hours
Average speed = 140 km / 10 hours = 14 km/h
