A train after traveling 50 kms from A meets with an accident and proceeds at 4/5th of the former speed and reaches B, 45 min late. Had the accident happened 20 kms further on, it would have arrived 12 mins sooner. Find the original speed and the distance.
Choose the correct answer:  A) 5 hrs 30 mins  B) 5 hrs 33 mins  C) 5 hrs 36 mins  D) 4 hrs 33 mins  E) 6 hrs 33 mins
speed = 25 kmph and distance = 125 kms.   scheduled time = 5 hrs.   Time taken in first case = 50/25 + 75/20 = 2+3.75=

<output>5.75</output>
5.75 hrs= 5 hrs 45 min   in second case, time taken = 70/25 + 55/20 = 111/20 hrs = 5 hrs 33 mins   ANSWER:5 hrs 33 mins
