It took a racer 300 second to run 3,000 meters. Based on the ratio given and using a double number line, how long did it take the racer to run 2,000 meters? (if you can, use a paper to draw the double number line, thank you)

200 seconds

1:2 ratio for 2,000 meters and 1:3 ratio for 3,000 meters

Step-by-step explanation:

It takes the racer 100 seconds to run 1,000 meters and there is 3'000 meters so you multiply 100 times 3 to get 300.
