A ship, 40 kilometers from the shore, springs a leak which admits \(3\frac{3}{4}\) tonnes of water in 12 minutes. 60 tonnes would suffice to sink her, but the ship's pumps can throw out 12 tonnes of water in one hour. Find the average rate of sailing, so that she may reach the shore just as she begging to sink?
\(1\frac{1}{2}\) km/hr
\(2\frac{1}{2}\) km/hr
\(3\frac{1}{2}\) km/hr
\(4\frac{1}{2}\) km/hr
