Melissa’s calculations of the tarantula found that the spider was able to cover 20 centimeters in 5 seconds, what was the average speed of the spider?

To find the average speed, divide the distance traveled by the time taken.

Average speed = distance/time

In this case, the distance covered is 20 centimeters and the time taken is 5 seconds.

Average speed = 20 cm / 5 sec = 4 cm/s

Therefore, the average speed of the spider is 4 centimeters per second.
