The three pictures you attached represent three different runs of the toy car.

Here's the data for the first run:

The change in time for the first quarter is 1.38 seconds.

The change in time for the second quarter is (2.19-1.38) = 0.81 seconds.

The change in time for the third quarter is (2.80 - 2.19) =  0.61 seconds.

The change in time for the fourth quarter is (3.31 - 2.80) = 0.51 seconds.

The quarters are all the same length, but the times are getting shorter.

The car must be getting faster !  

Maybe gravity is pulling it down, do ya reckon ?

Answer:

1.39

0.78

0.64

0.54

Explanation:

The answers are an average of the difference between times. The first one is different because it's the first checkpoint.

For example;

[tex]\frac{(2.19 - 1.38) + (2.14 - 1.39) + (2.2 - 1.41)}{3}[/tex]

[tex]\frac{.81 + .75 + .79}{3}[/tex]

[tex]\frac{2.35}{3}[/tex]

Divide 2.35 by 3, you get the answer, .78 seconds.
