Answer 1

Answer:

$89\text{ yards }\rightarrow\text{ up to 33 yards more}$

Explanation: There are two scenarios:

(1)

89 yards, and short of "power-pole":

(2)

122 yards and past the "power-pole"

Therefore the power pole must be between these two distances and we can have the range as:

$\begin{gathered} D_1=89\text{ yards} \\ D_2=122\text{ yards} \\ \Delta D=122-89=33\text{yards} \\ \end{gathered}$

Therefore the range of distances is from 89 yards up to 33 yards more, the power pole can be anywhere in between.
