Correct Answer: 12.1 seconds
Solution : Given: The distance of the train is (110 + 132) = 242 m and its speed is 72 km/h. We know that, $\text{Time}=\frac{\text{Distance}}{\text{Speed}}$ To convert km/h into m/s, we multiply by $\frac{5}{18}$. 72 km/h = $72\times \frac{5}{18}$ m/s = 20 m/s So, the time taken by the train to cross the bridge $=\frac{242}{20}=12.1$ seconds. Hence, the correct answer is 12.1 seconds.
