Calculation of Average Speed

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

The car traveled 600 meters in the first 40 seconds, 500 meters in the next 25 seconds, and 900 meters in the last 50 seconds.

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

The total distance traveled is the sum of the distances covered in each time interval: 600 meters + 500 meters + 900 meters = 2000 meters.

The total time taken is the sum of the time intervals: 40 seconds + 25 seconds + 50 seconds = 115 seconds.

Now, we can calculate the average speed by dividing the total distance traveled by the total time taken:

Average speed = Total distance / Total time = 2000 meters / 115 seconds.

Let's calculate the average speed:

Average speed = 2000 / 115 = 17.39 meters per second.

Therefore, the average speed of the car over the entire distance is approximately 17.39 meters per second.
