How long will a 110 meter long barge pass at a speed of 9 km / h past a 50 meter long motor ship?

Initial data: L1 (barge length) = 110 m; V1 (barge speed) = 9 km / h (2.5 m / s); L2 (length of the ship) = 50 m; for the calculation, we assume that the ship was stationary (V2 = 0 m / s).

The time of passage of the barge past the motor ship is determined by the formula: t = (L1 + L2) / V1.

Let’s make a calculation: t = (110 + 50) / 2.5 = 64 s.

Answer: The barge will pass the ship in 64 seconds.
