Saul is in germany, driving on the
autobahn. he drives 50 km in fifteen
minutes. how fast is saul driving?
a. 50 km/h
b. 100 km/h
c. 200 km/h
d. 400 km/h

 c

Explanation:Use equation for speed: V=S/t

S=50 km  -distance

t=15 min=0.25h  -time

V=?

V=S/t

V=50km/0.25h

V=200km/h

answer; /// the above statement is (true);

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
