When the 1 km long train is completely inside of the 3 km long tunnel, i.e., the last car has just entered the tunnel, then the train must travel another 2 km in 30 seconds.


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ x\ \frac{km}{hr}\ =\ \frac{2\,km}{30\,sec}\ \times\ \frac{3600\,sec}{hr}]


Do the arithmetic.
