A boat running upstream takes 8 hours 48 minutes to cover a certain distance, while it takes 4 hours to cover the same distance running downstream. What is the ratio between the speed of the boat and speed of the water current respectively?  Select the correct option:
A) 8/5  B) 8/3  C) 3/5  D) 5/8  E) 5/3
Let the man's rate upstream be x kmph and that downstream be y kmph.   Then, distance covered upstream in 8 hrs 48 min = Distance covered downstream in 4 hrs.   44 * x /5 = 4 * y   y = 11/5 * x   Required ratio = (y+x)/2 : (y-x)/2   = 8/5 : 3/5   = 8/3   Ans- 8/3
