Question

• always use significant figure rules. remember that these rules apply to all numbers that are measurements.

35 m is equivalent to how many km?
○ 0.035 km
○ 35000 km
○ 350 00 km
○ 0.0035 km

Explanation:

Step1: Recall the conversion factor

We know that \(1\space km = 1000\space m\), so to convert meters to kilometers, we use the conversion factor \(\frac{1\space km}{1000\space m}\).

Step2: Perform the conversion

We have \(35\space m\). To convert to kilometers, we multiply by the conversion factor:
\[
35\space m\times\frac{1\space km}{1000\space m}=\frac{35}{1000}\space km = 0.035\space km
\]
We also check significant figures. The original measurement \(35\space m\) has two significant figures, and \(0.035\space km\) also has two significant figures, which is consistent with the significant figure rules.

Answer:

0.035 km
