A train 180 m long is chugging along a railroad track going north. Along another railroad track, very near and parallel to the first, another train 100m long is trying to overtake the first at 180 km/hr. If the first train is running at 120 km/hr and its tail end is exactly 500 m ahead of the front of the second train, then find the following: a. How many meters have the first train traveled when the front end of the second train caught up with its end? b. How many meters have the second train traveled when its front end caught up with the tail end of the first train? c. How many seconds would have elapsed from the initial position when the second train has completely and clearly overtaken the first train?

A train 180 m long is chugging along a railroad track going north. Along another
railroad track, very near and parallel to the first, another train 100m long is trying
to overtake the first at 180 km/hr. If the first train is running at 120 km/hr and its tail
end is exactly 500 m ahead of the front of the second train, then find the following:
a. How many meters have the first train traveled when the front end of the
second train caught up with its end?
b. How many meters have the second train traveled when its front end caught
up with the tail end of the first train?
