Previous Question Next Question Question :

## A man can row 18 kmph in still water. it takes him thrice as long to row up as to row down the river.find the rate of stream.

Answer :

## Let man’s rate upstream be x kmph. then his rate downstream =3x kmph. So 2x=18 or x=9. Rate upstream=9 km/hr rate downstream=27 km/hr. Hence rate of stream=1/227-9km/hr=9 km/hr.

## A man can row 18 kmph in still water. It takes him thrice as long to row up as to row down the river. What is the rate of stream?

Answer (1 of 9): If the time taken upstream is three times the time taken downstream, then the speed downstream is three times the speed upstream Let speed of stream be y kmph (18 +y) = 3 ( 18-y) 18+y = 54 -3y 4y = 36 y = 9 kmph ANSWER

Let speed of stream = x

So downstreams speed = 18+x

And upstream speed = 18-x

It takes thrice the speed as long as to row up as to row down

So 3(18-x) =(18+x) 54-18 =4x x =36/4 x=9 km/h

So speed of stream is 9 km/h.

Given , man's rate in still water = 18 kmph

Let, a= x; b= 3x (a is down stream ,b is upstream)

Rate of steam = 1/a-b kmph

= 1/x-3x =1/-2x =2x

Man's rate in still water = 1/a+b kmph

18= 1/a+b a + b = 1/18 x +3x =1/18 4x = 1/18 2x = 9

Therefore , rate of stream is 9 kmph

Let the speed of the stream be v km/hr

Speed of rowing downstream = (18 + v) km/hr

Speed of rowing upstream = (18 — v) km/hr

Since it takes him thrice as long to row up as to row down the river,

Speed of rowing downstream = speed of rowing upstream

18 + v = 3(18 — v) 18 + v = 54 — 3v V = 9

Speed of river = 9 km/hr

Let the rate of stream = x km/hr. , speed upstream = (18-x)km/hr, and downstream

= (18+x) km/hr.

Time taken in rowing d kms. upstream = d/(18-x).

Time taken in rowing d kms. downstream = d/(18+x). , accordingly :-

{ d/(18-x) }. = 3 × { d/(18+x)}.

or, 18+x = 54 - 3.x

or, 4x = 36. => x = 36/4 = 9 km/hr. Answer.

Rate of flow of stream = 9 km/hr.

Method: EVEN THOUGH THERE SRE TWO UNKNOWN QUANTITIES HERE, (1) The distance travelled one way or the total time taken by the tower for crossing one way, and (2) the rate of flow of downstream; we need to assume only the second unknown as X km/hr flow rate, and we shall arrive at answer, WITHOUT HAVING TO WORRY ABOUT THE DISTANCE TRAVELLED OR TIME TAKEN ESCH WAY.

WITH X KM/HR FLOW RATE OF STREAM, the effective rate of rower UPSTREAM would be reduced by X km/hr, rresulting in net speed of (18-X ) km/hr. Going back DOWNSTREAM, the rowing rate would be increased by
