Chen rode his skateboard 3 and 3/4 miles in 3/4 of an hour what is his average speed in miles per hour

Answer 1

To find Chen's average speed in miles per hour, we need to divide the distance he traveled by the time it took him to travel that distance.

Distance = 3 3/4 miles = 15/4 miles
Time = 3/4 hour

Average speed = Distance / 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.
