Time taken by the engine to pump out 95 litres of water = 1 minute
Time taken by the engine to pump out 1 litre of water = 1 / 95 minutes
Time taken by the engine to pump out 13965 litres of water = 1 / 95 * 13965
= 13965 / 95 = 147
Therefore 147 minutes will be taken by the engine to pump out 13965 litres of water
