what do you think and why?

anonymous · Answer

I think it is The ant is crawling 4 feet per minute because it is speed and not distance

anonymous · Answer

exactly.  

We know that we have to have units of distance (feet) in order to get the right solution; the "4" is multiplied by t which has units of time (minutes), so "4" has to be in units of 
$$ \frac{feet}{minute}$$
which means that it's a speed ^_^  Good job!
