1 answer

Average speed = x2x1 /( t2t1)
Asuming this is the problem
the problem its divided in three parts. For segment A
A=1040/1.50 ( its 1040 because its moving downward)
AvgSpeed of segment A =20 km/h
Avg for segment B
AvgVb=2010/2.51.5
Avg speed of segmente B= 10km/h
Avg for C
avgVc=4020/3.02.5
Avg speed of segment C=40Km/h
The negative in segment A, means its moving downward...
hope it helps you... :) 👍
