Answer: The coach determines that Romeo needed to run 66.8 feet.
Step-by-step explanation:
Since we have given that
Distance from third base to home plate = 88.9 feet
Distance that away from third base when he was tagged out = 22.1 feet
According to question, the equation that can be used to determine how far he needed to run to get to home plate is given by
[tex]88.9-t=22.1\\\\here,\text{ t denotes the distance he needed to run to get to home plate.}\\\\88.9-22.1=t\\\\t=66.8\ feet[/tex]
Hence, The coach determines that Romeo needed to run 66.8 feet.
