Question 123941This question is from textbook Elementary and intermediate Algebra
: Avoing a collision. a car is traveling on a road that is perpeendicular to a railroad track.when the car is 30 meters from the crossing,the cars new collision detector warns the driver that is a train 50 meters from the car and heading toward the same crossing. how far is the train from the crossing? This question is from textbook Elementary and intermediate Algebra
You can put this solution on YOUR website! Since the road is perpendicular to the railroad track, and the collision detector measures the straight line distance from the car to the potential collision, you have two sides of a right triangle -- one of the legs and the hypotenuse.
The simple way to find the third side is to recognize that you have a 3:4:5 right triangle which tells you the third side has to be 40 meters.
