A jogger runs in a straight line with an average velocity of v1=6.6 m/s for t1=6.0 min, and then with an average velocity of v2=5 m/s for t2=3.0 min. What is her average velocity during this time? Answer in units of m/s.

distance1=velocity1*time1
distance2=velocity2*time2
avgvelocity=(distance1+distance2)/totaltime
