What is the fastest public transit to take from Davis Square to Harvard Square?<|im_end|>
<|im_start|>assistant
The fastest public transport option is to take the red line subway. This will cost $1 to $3 and will take approximately 7 minuets including the walk to and from the subway. If time is of the essence though it would be faster to take a cab, at about 3 minuets, as you would not have to walk at all. Though a cab will cost you about $10.<|im_end|>
