A ship is sinking and 120 more tons of water would suffice to sink it. Water seeps in at a constant rate of 2 tons a minute while pumps remove it at a rate of 1.75 tons a minutes. How much time in minutes has the ship to reach the shore before is sinks?

A ship 55 km from the shore springs a leak which admits 2 tonnes of water in 6 min . 80 tonnes of water would suffer to sink it, but the pumps can throw out 12 tonnes of water an hour. Find the average rate of sailing that it may just reach the shore as it begins to sink

From the top of a light house, it is observed that a ship is sailing directly towards it and the angle of depression of the ship changes from 30^(@) " to " 45^(@) in 10 minutes. Assuming that the ship is sailing with uniform speed, calculate in how much more time (in minutes) will the ship reach the light house?
