Thirty seconds pass from the time the last car has just completely entered the tunnel until the time when the front of the engine emerges from the other end. Determine the speed of the Snuggles, in km/h.
Answers: 3
), in meters per second, is the sum of the length of the tunnel (
), in meters, plus the length of the train (
), in meters, divided by time taken by vehicle to cross the tunnel completely (
), in seconds:
