Think of this as a triangle:
\n" ); document.write( "distance from the car to crossing (leg) = 30
\n" ); document.write( "distance from the car to the train (hypotenuse) = 50
\n" ); document.write( "distance from the train to the crossing (leg) = b
\n" ); document.write( " $\"a%5E2+%2B+b%5E2+=+c%5E2\"$
\n" ); document.write( " $\"30%5E2+%2B+b%5E2+=+50%5E2\"$
\n" ); document.write( " $\"b%5E2+=+1600\"$
\n" ); document.write( " $\"b+=+40\"$ The train is 40 meters from the crossing. \n" ); document.write( "
