A ship is sailing due to east at $\"\"$ when it passes the light house and

At the same time a ship is sailing due to west at $\"\"$ when it passes a point.

The two ships are $\"\"$ apart

Draw a diagram planes are travelling by north and south.

$\"\"$

Let time is $\"\"$ both are travells same time.

Where $\"\"$ is number of hours untill the ship travelling distance.

$\"\"$

Find time $\"\"$ .

Distance formula: $\"\"$ .

Let time $\"\"$ is number of hours untill they travelling distance $\"\"$ apart.

Make a table:

\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \

$\"\"$

Solve the equation.

Distance traveled by first ship plus distance traveled by second ship equals $\"\"$ .

$\"\"$ .

$\"\"$ (Original equation)

$\"\"$ (Simplify)

$\"\"$ (Divide each side by $\"\"$ )

$\"\"$ (Simplify)

Threfore, the two ships are $\"\"$ apart after $\"\"$ .

The two ships are $\"\"$ apart after $\"\"$ .
