Plug in what you know for your values. It is given that d is in meters and that r is in meters/minute and that it is multiplied by "t" so what must t be?

anonymous · Answer

C.meters per second

anonymous · Answer

or A.seconds

anonymous · Answer

Why would you say that?

anonymous · Answer

because its meters then minutes so wouldnt it be seconds after

anonymous · Answer

It is not asking what would be after? It is telling you that after is meters and that before you have meters/minute multiplied by something to get meters only

anonymous · Answer

$$meters = \frac{ meters }{ minute } \times t$$ What must t be so that you only have meters in your answer?

anonymous · Answer

meters

anonymous · Answer

Lets try it out...$$d = \frac{ meters }{ minute } \times t$$ if we say t is equal to meters then we have $$d = \frac{ meters }{ minute } \times meters$$ and then d would be$$d = \frac{ meters^2 }{ minute }$$

anonymous · Answer

We can obviously see that is not what they said d would be

anonymous · Answer

So which should be the answer so that you are only left with meters as your result?
