Answer: Mia's speed is 6.4 kilometers per hour.
Step-by-step explanation: Given that Mai is riding her bicycle she take 6 hours to ride 38.4 kilometers.
We are to find her speed.
We know that
\(\textup{Speed}=\dfrac{\textup{distance}}{\textup{time}}.\)
According to the given information, we have
distance = 38.4 kilometers and time = 6 hours.
Therefore, the speed of Mia is given by
\(S=\dfrac{38.4}{6}=6.4~\textup{kilometers per hour.}\)
Thus, Mia's speed is 6.4 kilometers per hour.
