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 1505 miles? Select.
A) Two hours and 30 minutes B) One hour and 10 minutes C) Two hours and 25 minutes. D) Three hours and 15 minutes E) Four hours and 20 minutes
let S1 and S2 be the speeds of train A and B   S1 is 350 and S2=28% less = 252   time taken = S1+S2/1505   which is   1505/602 =x   where 2&lt;x&lt;3   therefore Two hours and 25 minutes. !!
