Question

A train 540 meters long is running with a speed of 54 km per hour.In what time will it pass a tunnel 180 meters long

Answer 1

Answer:

48 sec. Time taken=distance travelled/Speed

Answer 2

Answer:

48 s

Step-by-step explanation:

Formula: Distance = Speed * Time

Distance = (540 + 180) = 720 m

Speed = 54 km/h

           = 54 * (5/18) m/s

           = 15 m/s

Time = 720/15 s

        = 48 s
