Final answer:
The monkey's average speed is 2.26 meters per second and its average velocity is 0.21 meters per second north.
Step-by-step explanation:
To calculate the monkey's average speed, we need to find the total distance traveled and divide it by the total time taken. In this case, the monkey traveled 48.28 meters north and 40 meters south for a total distance of 88.28 meters. The total time taken is 12 seconds north and 27 seconds south, which gives us a total time of 39 seconds. Average speed is distance divided by time, so the monkey's average speed is 88.28 meters / 39 seconds = 2.26 meters per second.
To calculate the monkey's average velocity, we need to find the total displacement and divide it by the total time taken. Displacement is the change in position, which is the final position minus the initial position. In this case, the monkey traveled 48.28 meters north and 40 meters south, resulting in a net displacement of 48.28 meters - 40 meters = 8.28 meters north. The total time taken is still 39 seconds. Average velocity is displacement divided by time, so the monkey's average velocity is 8.28 meters / 39 seconds = 0.21 meters per second north.
