A Colmar's train rails across an open track at 250 kilometers per hour. A regular passenger train travels at 68% of the Colmar's train speed. If the two trains start moving from the same station at the same time, how much time longer will it take the passenger train than the Colmar's to travel 850 kilometers? Answers:
A) 1 hour and 24 minutes.  B) 1 hour and 36 minutes.  C) 2 hours and 24 minutes.  D) 2 hours and 36 minutes.  E) 5 hours.
Difference in time = time taken by passenger train- time taken by Colmar's train   850/(250*68) *100 - 850/250   850 (100/ 250*68 - 1/250)   850*32/ (250*68)   1.6 hrs or 1 hr and 36 mins   1 hour and 36 minutes. is the answer
