Answer:

C is your answer.

Step-by-step explanation:

So Hiroki has -11.6, If you MINUS 11.6 off of your time you get better not worse. Karen has -5.2 so that one comes next. Juan has 0 so that means she didn't change, so that comes next. Isabelle has +3.2 which means she added 3.2 seconds to her previous record. And Gregor has +5.6 which means he added that much to his previous record.

Hope this helps you!!
