Answer:
We have to travel 26.93 units from platform B to C.
Step-by-step explanation:
Length of a segment having coordinates [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is determined by the formula,
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
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 = [tex]\sqrt{(-25+15)^2+(-20-5)^2}[/tex]
= [tex]\sqrt{100+625}[/tex]
= [tex]\sqrt{725}[/tex]
= [tex]5\sqrt{29}[/tex]
= 26.93 units
Therefore, we have to travel 26.93 units from platform B to C.
