<p>Let speed of boat B in still water = b</p>

<p>Speed of boat A in still water = 4b</p>

<p>4b − b = 21</p>

<p>3b = 21</p>

<p>b = 7<br>
Speed of boat A = 4 × 7 = 28</p>

<p>Upstream speed of A = 28 − stream</p>

<p>Downstream speed of B = 7 + stream</p>

<p>Distance = (speed of A upstream + speed of B downstream) × time</p>

<p>Distance( D ) = (28 − s + 7 + s) × 30</p>

<p>= (28 + 7) × 30</p>

<p>= 35 × 30</p>

<p>= 1050</p>
