A ship is heading towards the shore. When it is 32 miles from the shore, an aircraft whose speed is 15 times that of the ship is sent to deliver supplies. At what distance from the shore will the seaplane reach the ship?

The seaplane reaches the ship 30 miles from the shore.

Let the ship's speed be v, then the plane's speed is 15v.

They close the 32-mile gap at 16v, meeting after time 32/16v.

In that time the ship moves v x (32/16v) = 2 miles.

Distance from shore = 32 - 2 = 30 miles.
