**Hard Physics**

A bullet train is traveling at 23.3 m/s when it approaches a slower train 47 meters ahead traveling in the same direction at 6.67 m/s. If the faster train begins decelerating at 2.1m/s^2 while the slower train continues at constant speed, how soon will they collide? I got 3.68...

A train leaves New York at 1:00 PM. A second train leaves the same city in the same direction at 3:00 PM. The second train travels 28 mph faster than the first. If the second train overtakes the first at 6:00 PM, what is the speed of each of the two trains?
