It has been solved and explained by KD Live Experts under the guidance of Neetu Mam and they have tried to elaborate the concept used in Boats And Stream Questions.</p><h2 id="content-id-1506842793-3"><b>Question On Boats And Stream </b></h2>The speed of a boat in still water is v km/h and the speed of the stream is s km/h. The boat takes thrice as long to go a certain distance upstream as it takes to go the same distance downstream. If the speed of the boat in still water is increased by 2 km/h, the ratio of upstream to downstream speed becomes 1:2. Find the original speed of the stream (s).

</li><li><p>5 km/h</p>
</li><li><p>2 km/h</p>
</li><li><p>4 km/h</p>
</li><li><p>3 km/h</p>
</li></ol> <h2 id="content-id-1264370958-5"><b> Boats And Stream Questions Solution</b></h2><p>The correct answer is <strong>option 3</strong> i.e. <strong>2</strong> <strong>km/h</strong>.</p>

<p>Let distance = D</p>

<p>Upstream speed = v − s</p>

<p>Downstream speed = v + s</p>

<p>Time = Distance / Speed</p>

<p>Time upstream = 3 × Time downstream</p>

<p>D / (v − s) = 3D / (v + s)</p>

<p>v + s = 3(v − s)</p>

<p>v + s = 3v − 3s</p>

<p>2v = 4s</p>

<p>v = 2s</p>

<p>When the speed in still water increases by 2 km/h:</p>

<p>New upstream speed = v + 2 − s</p>

<p>New downstream speed = v + 2 + s</p>

<p>Given ratio:</p>

<p>(v + 2 − s) : (v + 2 + s) = 1 : 2</p>

<p>2(v + 2 − s) = v + 2 + s</p>

<p>2v + 4 − 2s = v + 2 + s</p>

<p>v + 2 = 3s</p>

<p>Substitute v = 2s</p>

<p>2s + 2 = 3s</p>

<p>s = 2 km/h</p>
