Shalnov [3]

Answer:

We have to travel 26.93 units from platform B to C.

Step-by-step explanation:

Length of a segment having coordinates $(x_1,y_1)$ and $(x_2,y_2)$ is determined by the formula,

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

From the graph attached,

Coordinates of the points B and C are (-25, -20) and (-15, 5) respectively.

Distance between these points B and C Or length of BC will be,

BC = $\sqrt{(-25+15)^2+(-20-5)^2}$

= $\sqrt{100+625}$

= $\sqrt{725}$

= $5\sqrt{29}$

= 26.93 units

Therefore, we have to travel 26.93 units from platform B to C.
