Amir ran the first 200-meter leg of the relay race with a speed of 8,260 millimeters per second. Ryder ran the last 200-meter leg with an average speed of 930 centimeters per second. Who ran the race faster, and how much faster was that person’s speed to the nearest meter per second?
Answer
A
Amir ran approximately 1 meter per second faster than Ryder.
B
Ryder ran approximately 1 meter per second faster than Amir.
C
Amir ran approximately 104 meters per second faster than Ryder.
D
Ryder ran approximately 104 meters per second faster than Amir.
Explanation
Convert both speeds to meters per second: Amir’s 8,260 millimeters per second is 8.26 meters per second, while Ryder’s 930 centimeters per second is 9.3 meters per second. Ryder’s speed is 9.3 − 8.26 = 1.04 meters per second faster, which rounds to 1 meter per second. So Ryder ran approximately 1 meter per second faster than Amir.
