Answer: The required number of miles rode is 4.6875.

Step-by-step explanation: We are given to solve the following situation for the value of d :

Tori needed to take a taxi. The fare for riding in a taxi is a $3 fixed charge and $0.80 per mile. The fare for a ride of d miles is $6.75.

According to the given information, we have

$3+0.80d=6.75\\\\\Rightarrow 0.80d=6.75-3\\\\\Rightarrow 0.80d=3.75\\\\\Rightarrow d=\dfrac{3.75}{0.80}\\\\\Rightarrow d=4.6875.$

Thus, the required number of miles rode is 4.6875.
