2 A cruise ship travels directly toward the dock with a velocity of 12 m/s relative to the water. A passenger walks 2 m/s in the same direction as shown in the picture below.
2 m's
12 m/s
According to the information and diagram, how far has the passenger traveled relative to the
dock after three seconds? This is a two-step problem.
42 m
Find the passenger's speed and then find the distance travelled.
Write the equation and show your work.

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day
