The train with a length of 240 m, moving evenly, passed the bridge in 2 minutes

The train with a length of 240 m, moving evenly, passed the bridge in 2 minutes. What is the speed of the train if the length of the bridge is 360 m?

The speed at which the train is moving is calculated using the following formula:

V = S / t, where S is the distance that the train will travel (the distance traveled will be equal to the sum of the lengths of the train and the bridge, respectively: S = S1 + S2, where S1 = 240 m, S2 = 360 m), t is the time the train travels along bridge (t = 2 min or 120 s).

V = (S1 + S2) / t.

Let’s do the calculation:

V = (240 + 360) / 120 = 600/120 = 5 m / s or 5 * 3.6 = 18 km / h.

Answer: The train speed is 5 m / s (18 km / h).
