<s>[INST] Jeremy is planning a road trip that is a certain distance \(D\) in length. He traveled a distance \(d_1\) of light to moderate traffic, then a distance \(d_2\) of moderate to heavy traffic, and finally a distance \(d_3\) of stop and go conditions. Assuming his speed for light to moderate traffic is \(v_1\), moderate to heavy traffic is \(v_2\), and for stop and go conditions is \(v_3\), what is his average speed \(V\) for the entire trip?[/INST]
