Final answer:
To calculate Megan's average speed, divide the distance she walked (1100 m) by the time it took (330 s), resulting in an average speed of approximately 3.333 m/s.
Step-by-step explanation:
Megan walks 1100 m to the left in 330 s. To find her average speed, we use the formula for speed which is the total distance traveled divided by the total time taken.
Average speed = Total distance ÷ Total time
In Megan's case, the total distance is 1100 m and the total time is 330 s.
Average speed = 1100 m ÷ 330 s = 3.333 m/s
Therefore, Megan's average speed is approximately 3.333 meters per second.
