Marks: +1, -0

A ship, 40 km from the shore, springs a leak which admits

3 3/4

tonnes of water in 12 min. 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 it may reach the shore just as it begins to sink.

$1 1/2$ km/h
$2 1/2$ km/h
$3 1/2$ km/h
$4 1/2$ km/h

Solution:

Ship will get 3.75 × 5 – 12 = 6.75 tonnes of water in 1 hr.
Time to admit 60 tonnes of water

{60}/{6.75}

hrs
∴ Required speed =

{40×6.75}/{60}

4 1/2

km/h
