terstate 10 You drive on 10 fros San Antario to t 60 k/h and the your average speed from San Antonio to Houston your average speed from Houston back to San Antonic? and What is your average speed for the entire trip? (d) What is your average velocity for the entire brip? (No Responsekm/h

Solution

a)

Average speed = total distance traveled/ time taken

So, Vav = (60*(t/2) + 153*(t/2))/(t)

= (60+153)/2

= 106.5 km/h <-----answer

b)

Average speed ,

Vav = (60*(t/2) + 153*(t/2))/(t)

= (60+153)/2

= 106.5 km/h <-----answer

c)

Average speed for entire trip:

Vavg =

(60*(t/2) + 153*(t/2) + 60*(t/2) + 153*(t/2)))/2t

= 106.5 km/h

d)

As the displacement is 0

So, the average velocity = 0 <------answer
