A 200m train enters the bridge at a speed of 18 km / h. Determine the time the train travels across the bridge if the bridge is 300m long.

Initial data: Lp (train length) = 200 m; V (the speed with which the given train entered the bridge) = 18 km / h or 5 m / s; Lm (bridge length) = 300 m.

To determine the travel time of a given train across the bridge, we use the following formula: t = S / V = (Lp + Lm) / V.

Let’s perform the calculation: t = (200 + 300) / 5 = 100 s or 1 min 40 s.

Answer: The travel time of a given train across the bridge is 1 min 40 s.
