How long does it take for the train to cross the 500 m long bridge? track length 120 m, train speed 60 km / h.

To find the time spent by the train to move on the bridge, we will use the formula: t = S / V = (Lm + Lp) / Vp.

Values of variables: Lm – length of the bridge (Lm = 500 m); Lp is the length of a given train (Lp = 120 m); Vp is the speed of the train on the bridge (Vp = 60 km / h = 16.67 m / s).

Let’s perform the calculation: t = (Lm + Lp) / Vp = (500 + 120) / 16.67 = 37.2 s.

Answer: The given train will take 37.2 seconds to pass the bridge.
