| **A train with a length of 360 m moves across the bridge at a speed of 36 km / h. How long does it take for a train to pass a 440 m long bridge?**

To calculate the duration of the passage of the bridge by the train under consideration, we apply the formula: t = S / V, where S is the length of the traveled path (S = Lm + Lp, where Lm is the length of the bridge along which the train moves (Lm = 440 m); Lp is its own length trains (Lp = 360 m)); V – train speed (V = 36 km / h, in SI V = 10 m / s).

Calculation: t = (Lm + Lp) / V = (440 + 360) / 10 = 800/10 = 80 s.

Answer: The train in question will pass the bridge in 80 seconds.
