Franklin wants to know how fast he runs different distances. He uses a stopwatch to measure the time it takes him to complete a 50-meter, 100-meter, and 200-meter race. How can he calculate his speed for each race?

• Add the distances and the times.

• Divide the distances by the times.

• Multiply the distances by the times.

• Subtract the distances from the times.
