Calculate the change in time for each quarter of the track. record the change in time in table e of your student guide. the change in time for the first quarter is seconds. the change in time for the second quarter is seconds. the change in time for the third quarter is seconds. the change in time for the fourth quarter is seconds.

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 !
