The speedometer of a european sportscar gives its speed in km/h. to the nearest integer, what is the car's speed in mi/h when the speedometer reads 282 km/h?

175  

Explanation:

v = speedometer reading of a european sportscar =

we know that,

1 km = 0.621 miles

So the speedometer reading of a european sportscar in  mi/h is given as

v = =

v = (282 x 0.621)

v = 175  

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
