Airplane B is located 5 miles due north of the airport at the same altitude as airplane A. Draw a diagram using coordinate system with origin O. How far apart are the two airplanes? Express the answer in radical form.

Use the distance formula to calculate how far apart A and B are. The distance formula is d=sqrt((x2-x1)^2+(y2-y1)^2), where (x1,y1) and (x2,y2) are the two points. -Doctor Jerry, The Math Forum Check out our web site! http://mathforum.org/dr.math/
