A concave mirror can produce either real or virtual images. Which is true reguarrinf the image distance? A)It is between the radius of curvature and the focal point.
B) It is closer to the Murrow than the focal Point.
C)It is at the focal Point.
D)It is farther away than the radius of curvature.

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

more than, less

less than, more

i really dont know but i will try okay.

so i think u would just add all them up and get your answer..
