Answer:
Mean
Step-by-step explanation:
I said mean because it would allow both Carl and Tamera to average their scores and compare one side by side rather than comparing 6 each which would just be time consuming and it seems like it wouldn't be any other choices.
458 turns/min ----- 13740/30 min
3206/7 (min) = 458
458 x 30 (min) = 13740
it is -1
2= 410x+14⇒4x+8=10x+14 ⇒6x=−6 ⇒x=−1
