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 need to divide the total distance he rode by the total time it took him to ride that distance.

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 / 3
Average speed = 5 miles per hour

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