The solar wind is made up of ions, mostly protons, flowing out from the Sun at about 400 km/s. Near Earth, each cubic kilometer of interplanetary space contains, on average, 6 x 10^15 solar-wind ions.

How many miles of ions are in a cubic kilometer of near- Earth space?

There are miles of ions in a cubic kilometer of near-Earth space.

Explanation:

In this context, we must be clear on stating that words miles is a synonym for thousands. In other words, the question may be rewritten to this form: How many thousand of ions are in a cubic kilometer of near-Earth space? In engineering notation, a thousand is represented by:

As we know the average quantity of solar-wind ions in a cubic kilometer of interplanetary space near Earth, we need to make quick conversion to determine the quantity of miles of ions by this formula:

Where:

- Quantity of solar-wind ions, measured in units.

- Quantity of solar-wind ions, measured in thousands (or miles).

If we know that , then:

There are miles of ions in a cubic kilometer of near-Earth space.

i'm pretty sure its b i might be wrong though!
