m/s
(b) You walk for 1.17 min at a speedof 1.22 m/s and then run for 1.17 minat 3.05 m/s along a straight track.
m/s

Answers

(a)here is your both distance are similaravg velocity=144.4/35.51=4.07m/s(b)1.17min=70.2sect2=70.2+70.2=140.4t1=0secd1=1.22*70.2=5.644d2=3.05*70.2=214.11avg velocity=(d2-d1)/(t2-t1)=208.47/140.4=1.48m/s.
