Question

The length of the fence along the car race track is 8,400 ft. If you plan to install 120 barricades, find how far apart should these barricades be from each other.

• A. 50 ft
• B. 60 ft
• C. 70 ft
• D. 75 ft

Answer 1

The correct option is C 70 ft

120 barricades should be installed along the path of 8,400 ft.

The distance between two barricades = $\frac{8400}{120}$

$$\begin{array}{c}70\\ 1208400\\ -\underset{–}{840}-1\\ 0000000\end{array}$$
Hence, barricades should be installed 70 ft apart.
