Question : A goods train 350 m long passes through a tunnel of 1250 m in 80 seconds. What is the speed of the train?
Option 1: 72 km/hr
Option 2: 64 km/hr
Option 3: 78 km/hr
Option 4: 56 km/hr
Correct Answer: 72 km/hr
Solution : Total distance = 350 + 1250 = 1600 m Total time = 80 s Speed = $\frac{\text{total distance}}{\text{total time}}$ = $\frac{1600}{80}$ = 20 m/s = $20 × \frac{18}{5}$ = 4 × 18 = 72 km/hr Hence, the correct answer is 72 km/hr.
