Question

Across a jungle trail that's 0.46 mile long, you install solar power lights to light up the path. How many lights are needed for the entire path, if you install one light at every 0.02 miles?

• A. 23
• B. 26
• C. 92
• D. 24

Answer 1

The correct option is A 23

Total length of the path = 0.46 miles.

Distance between two lights = 0.02 miles.

Number of lights needed = $\frac{0.46}{0.02}$

= $\frac{0.46}{0.02}$ $\times$ $\frac{100}{100}$ = $\frac{46}{2}$

= 23

Hence, 23 lights are needed.
