Explanation / Answer

(a) Average velocity between B and C
We know that average velocity is given by
= total displacement /total time
= (38.9-50.4)/10 = -1.15 m/s
(b) Now between C and D
= (-13.6 -38.9)/10 = -5.25 m/s
(c) Now between D and E
= (-38.1 - (-13.6)]/10 = -2.45 m/s
(d) Now between point A and E
= (-48.4 - 32.2)/10 = -8.06 m/s
