Answer: [tex]10^{-6}m[/tex]
Explanation:
We are asked to multiply 1 nano sec with 1 km/sec.
The conversion used from nano second to second
1 nsec = [tex]10^{-9}sec[/tex]
The conversion used from km to meters:
1 km = 1000 m
[tex]1nsec\times 1\frac{km}{sec}[/tex]
Putting the values we get:
[tex]10^{-9}sec\times {\frac{1000m}{sec}=10^{-9}\times 10^3m=10^{-6}m[/tex]
Therefore, the given conversion is [tex]10^{-6}m[/tex]
