Boats and Streams
A boat takes 19 hours for travelling downstream from point A to point B and
coming back to a point C midway between A and B. If the velocity of the stream is
4 kmph and the speed of the boat in still water is 14 kmph, what is the distance
between A and B?
Read Solution (Total 2)
-
- t1 + t2 =(d/(u+v))+(d/2(u-v))
19 = (d/18) + (d/2*10)
solve: d = 180 km - 4 years agoHelpfull: Yes(1) No(0)
- ncrn=22c19
22!/19!*3!=1540 - 4 years agoHelpfull: Yes(0) No(2)
