@johnweldon1993  can you help her idk how to do this

johnweldon1993 · Answer

Yeah sure :)

So an astronomical Unit can be converted to KM by using the fact that 

$$\large \frac{1 AU}{149,597,871 km}$$

So if that is true...we have 2000 AU we have

$$\large \frac{1 AU}{149,597,871 km} = \frac{2000}{x}$$

$$\large x = 2000 \times 149,597,871 = \space ?$$
