Question

4. A guardrail that runs along the

highway comes in sections that
are 10 meters long. If the
guardrail is 0.5 km long, how
many sections are there?

Answer 1

There are 50 sections.

Explanation:

Given,

Length of section = 10 meters

Total length of guardrail = 0.5 km

We will convert this length in meters.

1 km = 1000 meters

0.5 km = 0.5*1000 = 500 meters

Now,

No. of sections =
`(Total\ length\ of\ guardrail)/(Length\ of\ one\ section)`

No. of sections =
`(500)/(10)`

No. of sections = 50

There are 50 sections.
