Answer:1/2

Step-by-step explanation:Rate in still water = (1/2)*[(10/9) + (5/3)] m/sec.

Answer:5 kmph

Step-by-step explanation:Rate upstream = (750/675) = 10/9 m/sec

Rate downstream (750/450) m/sec = 5/3 m/sec

Rate in still water = (1/2)*[(10/9) + (5/3)] m/sec.

= 25/18 m/sec

= (25/18)*(18/5) kmph

= 5 kmph
