Chen rode his skateboard 3 3/4 miles in 3/4 of an hour. What was his average speed in miles per hour

Answer 1

To find Chen's average speed, we can divide the total distance traveled by the total time taken.

Total distance = 3 3/4 miles = 15/4 miles
Total time = 3/4 hour

Average speed = total distance / total time
Average speed = (15/4) / (3/4)
Average speed = (15/4) * (4/3)
Average speed = 15/3
Average speed = 5 miles per hour

Therefore, Chen's average speed was 5 miles per hour.
