One meter is equal to 10 9 nanometers. how long in meters is 670 nanometers? 6.70 × 10 –7 m
6.70 × 10 –11 m
6.70 × 10 9 m
6.70 × 10 –9 m

The answer to your question is: the first option

Explanation:

Meter is a unit of length in the SI, international system of units. Its symbol is m.

Nanometer is equivalent to 10⁻⁹ meters, as its name says it is used to measure  extremely small particles.

-To solve this problem we use a rule of three.

                             1 meter      ⇒     10⁹ nanometers

                             x meters    ⇒     670 nanometers

Simplify

                            x = (670 x 1)/( 10⁹)              

                            x = 6.7 x 10 ⁻⁷ meters
