D = 1.06 ( 212 − t ) A spacecraft heading for Pluto will take pictures of several other planets on its way. The above equation gives the distance, dd, in millions of kilometers, of the craft from its first photo opportunity with Mars in terms of the time, tt, in days. What is the meaning of the 212212 in this equation?

Group of answer choices:

The spacecraft travels 212 kilometers per day.

It will take the spacecraft 212 days to reach the Mars photo opportunity.

The spacecraft begins its journey 212 kilometers from the Mars photo opportunity.

After 212 days, the spacecraft will be within 1.06 kilometers of the Mars photo opportunity.
