Question 199908: Avoiding a collision. A car is traveling on a 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 toward the same crossing. How
far is the train from the crossing?
Answer by rfer(16322) (Show Source): You can put this solution on YOUR website!
use a^2+b^2=c^2
30^2+b^2=50^2
=40 meters
you don't have to do any math, you have a 3,4,5 triangle
so the side is 40 with no work
