Zach is making a round trip going from home to work. to get to her work she goes 30 m/s and then to get back home she goes 50 m/s. what is the velocityof zach for the entire round trip? a.0 m/s b.-20 m/s c.80 m/s

Vamos supor que o trajeto tem 300 metros:

Na ida ele faz o trajeto em:

t=300/50=30/5=6 s

Na volta:

t=300/30 = 10s

Somamos o tempo total:

t=10+6=16s

E a distancia total:

300.2 = 600

e fazemos:

v=600/16= 37,5 m/s

the following is queen elizabeth’s purposes:
