To solve this problem, we have to use the equation for constant movements.

[tex]d=v\cdot t[/tex]

Where v = 0.388 km/s and t = 2.5 s.

[tex]\begin{gathered} d=0.388\operatorname{km}/s\cdot2.5s \\ d=0.97\operatorname{km} \end{gathered}[/tex]

Therefore, the lightning has to strike 0.97 kilometers away in order to hear it after 2.5 seconds.
