Since a pedestrian covers 1 km in 10 minutes, their speed is 6 km/h. There are more oncoming trams than overtaking trams because the speed of the former relative to the pedestrian is greater than that of the latter. If we consider the pedestrian to be stationary, the speed of oncoming trams is the tram's speed \( V \) plus the pedestrian's speed. Therefore, the relative speed of oncoming trams is \( V + 6 \) and the relative speed of overtaking trams is \( V - 6 \). Clearly, the number of trams passing through a given point in a certain period is proportional to their speed. Thus, we have:

\[ 
\frac{V+6}{V-6} = \frac{700}{300} \rightarrow 3V + 18 = 7V - 42 \implies V = 15.
\]
