[@Techspert]Umm.... this is a race. You usually don't try to take out the competition  

[@DarkwolfX37] who did she know who should was throwing at? Also even with her partners directions she's blindfolded she wouldn't be able to see where to throw the shoe. Did she put the end spoon with the egg in her mouth?

She didn't. She just threw in the directions her partner told her. I put the target for the convenience of the other rpers, and to keep consistency with David's directions. 
She knew where to throw because of David's directions. You know how people will use a clock to represent directions relative to a person? Like when someone says "watch your six" it means "behind you," because you're considered the center of the clock? So David saying -"Kari, your first opponent is at two thirty three point five, moving at a slow rate that changes at approximately a tenth of a minute per second relative to you."- means that the target was at a 75+ degree angle to the right from where Kari was facing, and the rate of change was to show the change in position from where she's facing as time passed. She knew the direction of the goal, so him not specifying that it was a negative rate of change (as in, the "minutes" were going backwards in time) didn't affect her because she assumed her target was moving towards the goal. 
She put the spoon with the side holding the egg sideways in her mouth. Since spoons are bent the egg is still technically in/on the spoon, while actually being held in place by her teeth structure.
