... 
Draw a sketch ABCD as per the directions 
.. 
AB = 250 miles (east) 
BC = 300 miles ( north) 
CD= 700 miles (west) 
.. 
Draw a perpendicular from A meeting CA at D 
we have to find distance AD 
.. 
AD is the hypotenuse of the right triangle ADC 
AD = BC = 300 
DC= CA-CD but CD = AB= 250 So DC = 700-250= 350 miles 
AC^2= AD^2+DC^2 
AC^2= 300^2+350^2 
AC^2= 212,500 
AC = sqrt (212,500) 
461 miles
