Question : 117 of 200

Marks: +1, -0

A boat travels upstream from

B

to

A

and downstream from

A

to

B

in

3 {h}

. If the speed of the boat in still water is

9 {km} \/ {h}

and the speed of the current is

3 {km} \/ {h}

, what is the distance between

A

and

B ?

$6 {km}$
$4 {km}$
$8 {km}$
$12 {km}$

Solution:

Let the distance between

A

and

B

be

x

km.
Here, speed of stream

=3 {km} \/ {h}

Speed of boat

=9 {km} \/ {h}

According to the question,

\;{x}/{9-3}+\;{x}/{9+3} \;\; =3

⇒ \;{x}/{6}+\;{x}/{12} \;\; =3

⇒ 3 x \;\; =36

∴ x \;\; =12 {km}

Therefore, distance between

A

to

B

is

12 {km}

.
