A boat running downstream covers a distance of 16 ~km in 2 hours while for covering the same distance upstream, it takes 4 hours. What is the speed of the boat in still water?

Options

  1. A4 ~km / hr
  2. B6 ~km / hr
  3. C8 ~km / hr
  4. DData inadequate

Correct answer

B. 6 ~km / hr

Step-by-step solution

Rate downstream = ( 16 2 ) kmph =8 kmph ; Rate upstream ( 16 4 ) kmph =4 kmph . Speed in still water = 1 2 (8+4) kmph =6 kmph
