A car is traveling on a road that is perpendicular to a railroad track. When the car is 30 meters from the crossing, the cars new collision detector warns the driver that there is a train 50 meters from the car heading toward the same crossing. How far is the train from the crossing?\r
\n" ); document.write( "\n" ); document.write( "Well for this problem you use the Pythagorean theorem. here your a is 30 and your c is 50 so, if you know your Pythagorean triples you know that the other leg, b, is 40 meters long. if not you solve the simple equation:\r
\n" ); document.write( "\n" ); document.write( "30^2 + b^2 = 50^2
\n" ); document.write( "900 + b^2 = 2500
\n" ); document.write( "b^2 = 1600
\n" ); document.write( "b = 400\r
