A car travels 100km in 8hours and the remaining 40km in 2hours
To find the average speed of the car, we need to use the formula:
Average speed = Total distance / Total time
Total distance = 100 km + 40 km = 140 km
Total time = 8 hours + 2 hours = 10 hours
Therefore, the average speed of the car is:
Average speed = 140 km / 10 hours = 14 km/h
