We can set up a proportion to find the answer:

400 meters / 5 seconds = 600 meters / x seconds

Cross-multiplying, we get:

400x = 5 * 600

Simplifying, we get:

400x = 3000

Dividing both sides by 400, we get:

x = 3000 / 400

x = 7.5 seconds

Therefore, Danni will be able to complete a race that is 600 meters in 7.5 seconds.
