Answer:
Step-by-step explanation:
Whole race was 12 meters
Jody:
12-3=9
To get to 8 meters, Jodi took 8 sec, so to get to 9, Jodi took 9 sec. SO YOUR ANSWER IS WRONG!
Carson:
Started at 0.
12/3=4
4*2=8 seconds!
Answer:
Carson won with a time of 8 seconds
Jody 2 x 2=4 4x12=48 48÷2 =24
Carson 3x2=6 6x12=72 72÷9=8
