heres a pic of whats going on: http://img405.imageshack.us/img405/415/untitledyp4.jpg

Ship A travels south at a speed of 8 miles/hr,

Ship B travels east at a speed of 16 miles/hr.

The pic shows both ships at 7am.

with matlab, plot the distance between the ships as a function of time for the next 4 hours.

the horizontal axis will show the time of day starting at 7.

and the vertical will show the distance.

'If visiblity is at 8 miles, estimate the time when the people on both ships can see each other.'

..this may be a d=r*t problem.

dunno, how to set it up correctly.

thanks for any help.
