Two trains are traveling on a collision course. If train A is traveling at a speed of 350 mph and train B is traveling 28% slower, how much time will it take the trains to collide if the initial distance between the two is 1655.5 miles?	Answers:  A) Two hours and 30 minutes.  B) One hour and 10 minutes.  C) Two hours and 45 minutes.  D) Three hours and 15 minutes.  E) Four hours and 20 minutes.
Answer is C. Two hours and 45 minutes.   Since they are racing towards each other, the speed is accumulative, ie. 350 mph + 350*0.72 = 602 (0.72 because the second train is 28% slower)   So time before collision is total distance / total speed = 1655.5/602 = 2 hours and 45 mins
