A ship arrives at the mouth of a river in water of density 1016 kg per cu. m with a freeboard of ‘S’ m. She then discharges 150 tonnes of cargo, and proceeds up river to a second port, consuming 14 tonnes of bunkers. When she arrives at the second port the freeboard is again ‘S’ m, the density of the water being 1004 kg per cu. m. Find the ship’s displacement on arrival at the second port.
