Question

A monkey takes a trip. The monkey walks upright for 43 seconds and travels 57.62 meters. He then runs on all fours for 15 seconds and travels 46.95 meters. He then swings from vine to vine for 21 seconds and travels 58.59 meters. Calculate the total distance traveled and the average speed for the entire trip.

a) Total distance: 163.16 meters, Average speed: 2.54 m/s
b) Total distance: 163.16 meters, Average speed: 4.87 m/s
c) Total distance: 163.16 meters, Average speed: 7.79 m/s
d) Total distance: 163.16 meters, Average speed: 9.42 m/s

Answer 1

The total distance traveled by the monkey is 163.16 meters. However, using the correct method of dividing the total distance by the total time (79 seconds) gives an average speed of approximately 2.07 m/s, which indicates that all the provided options are incorrect.

Step-by-step explanation:

The student's question involves calculating both the total distance traveled by the monkey and the average speed for the entire trip. To find the total distance, we simply add the distances traveled during each phase of the journey:

• Walking: 57.62 meters
• Running: 46.95 meters
• Swinging: 58.59 meters

Therefore, the total distance traveled is 57.62 + 46.95 + 58.59 = 163.16 meters.

To find the average speed, we add up the total time spent on the trip and then divide the total distance by the total time:

• Walking time: 43 seconds
• Running time: 15 seconds
• Swinging time: 21 seconds

Total time = 43 + 15 + 21 = 79 seconds.

Average speed = Total distance / Total time = 163.16 meters / 79 seconds ≈ 2.07 m/s.

Since none of the provided options offer an average speed of 2.07 m/s, they must all be incorrect.
