Question

the earth completes a circular orbit around the sun in one year. the orbit has a radius of 93,000,000 miles. what is the speed of the earth around the sun in m/s? Report your result using scientific notation.

Answer 1

29,800.85 m/s or 2.98 x 10^4

Step-by-step explanation:

1 mile is 1609.34 Meters

1 year is 31,536,000 seconds

1609.34 x 93,000,000 = radius in meters= 149,668,620,000

2 x pi x r = circumference and or distance traveled

2 x pi x 149,668,620,000

distance traveled / time it takes to travel the distance = speed or velocity

940,395,674,129.84 / 31,556,000 = 29,800.85 m/s or 2.98 x 10^4
