a car travelled 100km in 8hours and the remaining 40km in 2hours.calculate the average speed
average speed is totaldistance/totaltime:
(100+40)/(8+2) = 14 km/hr
more like a bicycle, at that speed.

To calculate the average speed, we need to divide the total distance traveled by the total time taken.
The total distance traveled is the sum of the distance traveled in the first part (100 km) and the distance traveled in the second part (40 km), which is 100 km + 40 km = 140 km.
The total time taken is the sum of the time taken in the first part (8 hours) and the time taken in the second part (2 hours), which is 8 hours + 2 hours = 10 hours.
Dividing the total distance (140 km) by the total time (10 hours) gives us the average speed:
Average speed = Total distance / Total time
Average speed = 140 km / 10 hours
Average speed = 14 km/h
Therefore, the average speed of the car is 14 km/h.
To calculate the average speed, you need to divide the total distance traveled by the total time taken.
In this case, the car traveled 100 km in 8 hours and another 40 km in 2 hours.
To find the total distance traveled, you add the two distances together:
100 km + 40 km = 140 km
To find the total time taken, you add the two times together:
8 hours + 2 hours = 10 hours
Now, you can calculate the average speed by dividing the total distance (140 km) by the total time (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 car is 14 km/h.
