Question

Andrew started at home. For the first 15 minutes he traveled at a constant speed and traveled a total of 4 miles. For the next 10 minutes Andrew rested. Andrew then rode his bike home which took 20 minutes. What was Andrew's average speed on his way home?

Answer 1

To calculate Andrew's average speed on his way home, divide the total distance traveled by the total time taken.

Step-by-step explanation:

To calculate Andrew's average speed on his way home, we need to know the total distance he traveled and the total time it took him. From the information given, we know that Andrew traveled a total of 4 miles on his way home and it took him 20 minutes. To find the average speed, we divide the total distance traveled by the total time taken: Average speed = Total distance / Total time

Average speed = 4 miles / 20 minutes = 0.2 miles per minute

Therefore, Andrew's average speed on his way home is 0.2 miles per minute.
