36km/hour = 10m/second Assuming you're calculating the time taken from the moment the front of the train enters the tunnel to the time when the back of the train exits the tunnel, you're looking at a total distance of 180+180+90 = 450m Hence the time taken to pass through the tunnel completely would be 450/10 = 45secs.
If you are timing from when the train first enters the tunnel until the last car exits the tunnel, then the train would travel 2 miles during this time.So 2 mi / (15 mi/hr) = (2/15) hr * 60 (min/hr) = 8 minutes
From the time the front of the locomotive enters the tunnel . . .-- The front of the locomotive traverses the 1-mile tunnel, bringing the center of the train to the entrance.-- The center of the train traverses the 1-mile tunnel, bringing the end of the train to the entrance.-- The end of the train traverses the 1-mile tunnel.In all, the train has to travel 3 miles. At the rate of 12 mph, it takes (3/12) = 1/4 hour = 15 minutes.
