Using system of linear equations the distance at the fisherman and the bobbler meets ls 8 miles

Speed in still waters = 7 mph

Stream speed = 3 mph

Upstream speed of canoe = 7 - 3 = 4 mph

<em>Distance</em><em> </em><em>between</em><em> </em><em>fisherman</em><em> </em><em>and</em><em> </em><em>bobbler</em><em> </em><em>=</em><em> </em><em>14</em><em> </em><em>miles</em><em> </em>

Let seperation distance = d

Meeting distance = 14 - d

<u>using the relation</u> :

<em>Distance= (speed × time)</em>

canoe distance , <em>d = </em><em>4t</em><em> </em><em>-</em><em> </em><em>-</em><em> </em><em>-</em><em> </em><em>-</em><em> </em><em>(</em><em>1</em><em>)</em>

Noobler distance = <em>14 - d = 3t </em><em>-</em><em>-</em><em>-</em><em>-</em><em>(</em><em>2</em><em>)</em>

Equate (1) and (2)

d/4 = (14 - d)/3

3d = 4 (14 - d)

3d = 56 - 4d

7d = 56

d = 8 miles

Hence, the distance is 8 miles
