Chen rode his skateboard 3 3/4 miles in 3/4 pf an hour. what was his speed in miles per hours
To find Chen's speed in miles per hour, we need to divide the distance he traveled by the time it took him to travel that distance.
Distance traveled: 3 3/4 miles
Time taken: 3/4 hours
Speed = Distance / Time
Speed = (3 3/4) / (3/4)
Speed = (15/4) / (3/4)
Speed = (15/4) * (4/3)
Speed = 5 mph
Therefore, Chen's speed was 5 miles per hour.
