    The pigeon is doing exactly what the problem says- flying back and forth between the two cars at 36 km/h. Meanwhile, the two cars are moving toward each other at 16 and 25 km/h. The cars are initially 400m apart. How long will it take them to crash together? (Of course, the pigeon, always being between the two cars will be killed in the collision but try not mourn too long!) In that time how far (total distance) will the pigeon have flown? The second part of the question is a little harder- what is the "net distance", that is the distance from the pigeon initial position, on the first car which is driving at 16 km/h to the point where the two cars collide.
