A man rows down stream 22km and 7 km upstream. if he takes 6 hrs to covereach distance, then the velocity of the current is	Choose the correct answer
A) 0.5kmph
B) 1.25kmph
C) 8.5kmph
D) 6.3kmph
E) 4.9kmph
Rate down stream=(22/6)kmph;   Rate up stream=(7/6)kmph;   velocity of the current =1/2(22/6-7/6)kmph   =1.25kmph   Answer(1.25kmph)
