James built a small electric car and recorded the distance it traveled. The table below shows the distance traveled (n) during t
he 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
This question seems to me to be an exercise in applying the rule for a difference of squares in order to rewrite the difference of two relatively large numbers as the "simpler" product of other integers.
