Length of train : 100
length of bridge : 400
distance covered by the train to cross the bridge : (100 + 400) = 500
time taken by the train to cross : 30
speed = distance / time
speed = 500/30
speed = 16.67 meters per second <===
Answer:
I believe the answer is the system has one solution. Both lines have the same y-intercept. And the solution is the intersection of the 2 lines.
