Question 45536: Avoiding a collision. A car is traveling on the road that is perpendicular to a railroad track. When the car is 30 meters from the crossing, the car’s new collision detector warns the driver that there is a train 50 meters from the car and heading towards the same crossing. How far is the train from the crossing? Please show work as well as solution. Thank you. Answer by Nate(3500) (Show Source):
You can put this solution on YOUR website! Think of this as a right triangle.
The crossing is the point at which the right angle is located.
Crossing to car is a leg, and from the crossing to the train is the other leg.
Leg: 30
Leg: a
Hypotenuse: 50
40 meters from the crossing
