Part A.) The midpoint between the two speeds is just an estimate of the exact average speed. This is not exactly 27 m/s because although they have the same distance, they differ in speed. So, the answer is more or less, but not equal to, 27 m/s.
Part B.) The average speed is the total amount of distance traveled per total time.
Convert miles to meters: 1 mile = 1,609.34 meters
8 miles* 1,609.34 m/1 mile = 12,874.72 m
Average Speed = (12,874.72 m + 12,874.72 m)/[(12,874.72 m/24 m/s)+ (12,874.72 m/30 m/s)]
Average speed = 26.67 m/s
Globalization connects foreign powers, increases trade, creates new industries, provides jobs, and modernizes countries.
Answer:
true
Explanation:
Gravity (or the acceleration due to gravity) is 9.81 meters per second squared, on the surface of Earth, because of the size of Earth and the distance we are on its surface from its center.
