Question

earth rotates on an axis through its pkoes. the distance from the axis to the location on Earty 30 degrees noth latitude is about 3429.5 miles. Therefore, a location on Earth 30 degrees north latitutde is spinning on a circle of radus 3429.5 miles. compute the linear speed on the surface of Earth at 30 degrees north latitude

Answer 1

Answer: The answer is 897.96 mph (miles per hour)

Explanation:

The 30 degrees north latitude spinning on a circle of radius 3429.5 miles makes one full circle each day. And 24 hours makes 1 day.

The distance travelled is the perimeter or circumference of the circle which is equal to :

d = 2πr. Where π= 3.142 and r= 3439.5.

d= 2 × 3.142 ×3429.5

d= 21550.978

Linear speed= distance/ time

Linear speed= 21550.978/24

Linear speed= 897.96 mph
