.
{{{D[1]=60(1/3)=20}}}miles
{{{D[2]=30(1/2)=15}}}miles
Total distance traveled={{{20+15=35}}} miles
Total time traveling={{{5/6}}}hr
Average speed:{{{S=35/(5/6)=42}}}mph

Let positive x be East.
Let positive y be North.
Starting position:({{{0}}},{{{0}}})
East displacement:({{{20}}},{{{0}}})+({{{15}}},{{{0}}})
Final position:({{{0}}},{{{0}}})+({{{35}}},{{{0}}})=({{{35}}},{{{0}}})
Time:{{{5/6}}}hr
{{{V=X/t}}}
Average velocity:{{{V}}}=({{{42}}},{{{0}}})
