Answer 1

To solve this problem, we can use the formula: speed = distance / time.

We know that Danni drove 400 meters in 5 seconds. Using the formula, we can calculate her speed: speed = 400 meters / 5 seconds = 80 meters/second.

To find out how long it will take Danni to complete a race that is 600 meters, we can use the formula: time = distance / speed.

Substituting the values, we get: time = 600 meters / 80 meters/second = 7.5 seconds.

Therefore, the correct answer is 7.5 seconds.
