Answer 2

1.39

0.78

0.64

0.54

Step-by-step explanation:

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

For example;

`((2.19 - 1.38) + (2.14 - 1.39) + (2.2 - 1.41))/(3)`

`(.81 + .75 + .79)/(3)`

`(2.35)/(3)`

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