SUMMARY
The average speed of a car accelerating from a constant speed of 11 m/s with an acceleration of 1.9 m/s² over a period of 10 seconds is calculated using the formula for average speed during acceleration. The correct approach involves determining the final velocity after acceleration, which is 11 m/s + (1.9 m/s² * 10 s) = 30 m/s. The average speed is then (initial speed + final speed) / 2, resulting in an average speed of 20.5 m/s during the acceleration period.
