SUMMARY
The average speed of a motorcycle traveling up a hill at 10 miles per hour and down at 25 miles per hour is not calculated by simply averaging the two speeds. Instead, the correct method involves determining the total distance traveled and the total time taken. The average speed is defined as total distance divided by total time, leading to a final average speed that is lower than the naive average of 7.5 miles per hour. This discussion highlights a common misconception in calculating average speed in scenarios involving different speeds for equal distances.
