Show answer & explanation
Correct answer: C
Answer: 2 hours
Reason:
Total distance the train must travel to completely cross the tunnel = tunnel length + train length = 58 km + 2 km = 60 km.
Speed of the train = 30 km/hr.
Time = distance ÷ speed = 60 ÷ 30 = 2 hours.
Therefore, the time taken to cross the tunnel is 2 hours.
