Question

earth completes its 584-million-mile orbit of the sun in about 365 days. how fast is earth moving through its orbit in miles per hour?

Answer 1

66666.67 miles/hr

Explanation:

Given that:

Earth complete its orbit of the Sun which is 584 million miles

Time taken to complete the orbit = 365 days

To find:

Speed of earth in miles per hour = ?

Solution:

First of all, we need to convert the distance in miles and time in hours to get our answer.

Let us have a look at the conversion units:

1 day = 24 hours

So, 365 days = 24
`*` 365 hours = 8760 hours

Distance traveled = 584 million miles

1 million miles = 1000000 miles

584 million miles = 584000000 miles

Formula for speed is given as:

`Speed = (Distance)/(Time)`

Let us put the values of Distance and time given in miles and hours to get the speed in miles/hr.

`Speed = (584000000)/(8760)\\\Rightarrow \bold{Speed = 66666.67\ miles/hr}`

So, the answer is: 66666.67 miles/hr
