(2) On a certain section of railway, there are three stations $A$, $B$, and $C$ in sequence, with $A B=5 \mathrm{~km}$ and $B C=3 \mathrm{~km}$. According to the train schedule, the train is supposed to depart from station $A$ at 8:00, arrive at station $B$ at 8:07 and stop for 1 minute, and arrive at station $C$ at 8:12. In actual operation, assume the train departs from station $A$ on time, stops for 1 minute at station $B$, and travels at a constant speed of $v \mathrm{~km} / \mathrm{h}$ while moving. The absolute value of the difference between the actual arrival time of the train at a station and the scheduled time is called the operation error of the train at that station.
(1) Write down the operation errors of the train at stations $B$ and $C$;
(2) If the sum of the operation errors at stations $B$ and $C$ is required to be no more than 2 minutes, find the range of values for $v$.
(2) (1) The running error at station $B$ is $\left|\frac{300}{v}-7\right|$ minutes, and the running error at station $C$ is $\left|\frac{480}{v}-11\right|$ minutes
(2) $\left[39, \frac{195}{4}\right]$
