danni races cars at her local racetrack She drove her red car 400 meters in 5 seconds if she drives the same car at the same time how fast will she be able to complete a race that is that is 600 meters. (1 point)
1. 40 seconds
2. 7.5 seconds
3. 3.33 seconds
4. 200 seconds
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.
To find out how fast Danni will complete the 600-meter race, we first need to find her speed in meters per second. We can do this by dividing the distance (in meters) by the time (in seconds) taken to cover that distance.
Danni's speed in meters per second:
Speed = Distance / Time
Speed = 400 meters / 5 seconds
Speed = 80 meters/second
Now, to find the time it will take Danni to complete the 600-meter race, we can divide the distance by her speed.
Time = Distance / Speed
Time = 600 meters / 80 meters/second
Time = 7.5 seconds
Therefore, Danni will be able to complete the 600-meter race in 7.5 seconds. The answer is option 2.
