Respuesta :

Given:

The distance travelled by Tracy till she stopped to smell roses, x=90 feet.

The distance from roses to the friend, y=200 yards.

The distance travelled by Tracy one side,

[tex]\begin{gathered} D=x+y \\ =90\text{ f}eet+200\times3feet \\ =90\text{ f}eet+600\text{ f}eet \\ =690\text{ f}eet \end{gathered}[/tex]

(1 yard=3 feet).

Now, the total distance travelled byTracy both sides is,

[tex]\begin{gathered} d=2D \\ =2\times690\text{ f}eet \\ =1380\text{ f}eet \end{gathered}[/tex]

Therefore, Tracy walk was 1380 feet long.
