Answer:
circumference of earth = 24000 miles
Explanation:
given data
New York and Los Angeles distance = 3000 mi
time difference = 3 h
to find out
circumference of the Earth
solution
we find speed first that is
speed = [tex]\frac{distance }{time}[/tex]
speed = [tex]\frac{3000}{3}[/tex]
speed = 1000 mph
now we know speed of earth is
speed = [tex]\frac{circumference of earth}{time of rotation}[/tex]
so
circumference = speed × time of rotation
and we know earth take 24 hours to rotate at its axis
so
circumference of earth = 1000 × 24
circumference of earth = 24000 miles
