How many feet long was Tracy's walk? feet Submit

Answer 1

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,

`\begin{gathered} D=x+y \\ =90\text{ f}eet+200*3feet \\ =90\text{ f}eet+600\text{ f}eet \\ =690\text{ f}eet \end{gathered}`

(1 yard=3 feet).

Now, the total distance travelled byTracy both sides is,

`\begin{gathered} d=2D \\ =2*690\text{ f}eet \\ =1380\text{ f}eet \end{gathered}`

Therefore, Tracy walk was 1380 feet long.
