James built a small electric car and recorded the distance it traveled. The table below shows the distance traveled (n) during the first 4 seconds after starting (f). Elapsed Time(seconds) Distance Traveled(feet)1 6.22 12.43 18.64 24.8Which of the following equations represents the relationship between the distance traveled and the elapsed time? f = 6.2 + n n = 6.2 + f f = 6.2n n = 6.2f
Question
Answer:
TableElapsed Time (seconds) Distance Traveled (feet)
1 6.2
2 12.4
3 18.6
4 24.8
Explanation:
You can check that 6.2 / 1 = 12.4 / 2 = 18.6 / 3 = 24.8 / 4 = 6.2
So, the relationship between the distance traveled and the time elapsed is a constant:
distance traveled / time elapsed = 6.2
n / f = 6.2
=> n = 6.2 f
Answer: n = 6.2 f
