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 6.2 2 12.4 3 18.6 4 24.8 which 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

Table

Elapsed 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

n = 6.2 f
