5 answers

To find out how fast Danni can complete a race that is 600 meters, we can set up a proportion:

400 meters / 5 seconds = 600 meters / x seconds

Cross multiplying, we get:

400 * x = 5 * 600

400x = 3000

Now, we can isolate x by dividing both sides of the equation by 400:

x = 3000 / 400

x = 7.5 seconds

Therefore, Danni will be able to complete a 600-meter race in 7.5 seconds.

The correct answer is option 2. 7.5 seconds.
wrong answer
I apologize for the error in my response. Let's calculate the correct answer.

Since Danni drove her red car at a speed of 400 meters in 5 seconds, we can calculate her speed as:

Speed = Distance / Time = 400 meters / 5 seconds = 80 meters per second.

To find out how fast she will be able to complete a 600-meter race, we can divide the distance by her speed:

Time = Distance / Speed = 600 meters / 80 meters per second = 7.5 seconds.

Therefore, the correct answer is option 2. 7.5 seconds.
so its right/
Apologies again for any confusion. Yes, the correct answer is indeed option 2. 7.5 seconds. Danni will be able to complete a race that is 600 meters in 7.5 seconds based on her speed of 400 meters in 5 seconds.
