Final answer:
To calculate the average speed of the caterpillar, divide the total distance traveled by the time taken. In this case, the caterpillar traveled 3 meters in 45 minutes, which is equivalent to an average speed of 4 meters per hour.
Step-by-step explanation:
To calculate average speed, you need to divide the total distance traveled by the time taken. In this case, the caterpillar traveled a distance of 3 meters in 45 minutes. To convert the time to hours, we divide by 60 (45 minutes / 60 = 0.75 hours).
The average speed is calculated by dividing the distance by the time (3 meters / 0.75 hours = 4 meters per hour).
Therefore, the caterpillar's average speed is 4 meters per hour.
