Distance = Rate * Time
\n" ); document.write( "\"D%5B1%5D=15%2AT\"
\n" ); document.write( "\"D%5B2%5D=20%2AT\"
\n" ); document.write( "Since one is going north and the other is going east, their distances are legs of a right triangle and the distance between them is the hypotenuse of the right triangle. Use the Pythagorean theorem.
\n" ); document.write( "\"D%5E2=D%5B1%5D%5E2%2BD%5B2%5D%5E2\"
\n" ); document.write( "\"D%5E2=%2815T%29%5E2%2B%2820T%29%5E2=75%5E2\"
\n" ); document.write( "\"225T%5E2%2B400T%5E2=5625\"
\n" ); document.write( "Take it from there to solve for \"T\"
