Question

Fathom is a unit once used by sailors to measure the depth of water. If a sunken ship was located underwater at $240$ feet, which expression would describe the location of the ship in fathoms?
$1fathom=6feet$

• A. $240\times 6$
• B. $240÷6$
• C. $240-6$
• D. $240+6$

Answer 1

The correct option is B $240÷6$

We have $1fathom=6feet$
$1feet=\frac{1}{6}fathom$
Ship was located underwater at $240$ feet
$\therefore$ location of ship underwater in fathoms $=240÷6$
