Question

Jordan takes his bicycle out for 5 hours. For the first 3 hours, he rides his bicycle at 10 miles per hour. He stops to rest for 1 hour and then continues his ride. For the last hour he rides at a speed of 20 miles per hour. What was Jordan’s average speed for the entire 5 hour period?

Answer 1

To find Jordan's average speed for the 5 hours, calculate the total distance traveled and divide it by the total time taken. In this case, the average speed is 12.5 miles per hour.

Step-by-step explanation:

To calculate Jordan's average speed for the entire 5-hour period, we need to determine the total distance he traveled and the total time it took him.

For the first 3 hours, Jordan traveled at 10 miles per hour, so he covered a distance of 10 miles/hour × 3 hours = 30 miles.

For the last hour, he traveled at 20 miles per hour, covering a distance of 20 miles/hour × 1 hour = 20 miles.

Therefore, his total distance covered is 30 miles + 20 miles = 50 miles.

The total time he took is 3 hours + 1 hour = 4 hours.

To calculate his average speed, we divide the total distance by the total time: 50 miles ÷ 4 hours = 12.5 miles per hour.

Therefore, Jordan's average speed for the entire 5-hour period is 12.5 miles per hour.
