Question

Earth rotates on its axis every 24 hours. Through how many degrees does a point on the equator travel in one hour? Through how many degrees does a point on the equator travel in one week?

Answer 1

360 degrees in one hour

Step-by-step explanation:

The Earth completes one full rotation on its axis in approximately 24 hours. This means that in one hour, the Earth rotates 360 degrees (a full circle).

To calculate how many degrees a point on the equator travels in one week, we need to calculate the rotation for one hour and then multiply it by the number of hours in a week.

Degrees in one hour = 360 degrees

Hours in one week = 24 hours/day * 7 days/week = 168 hours

Degrees in one week = Degrees in one hour * Hours in one week

Degrees in one week = 360 degrees * 168 hours = 60,480 degrees

So, a point on the equator travels 360 degrees in one hour and 60,480 degrees in one week due to Earth's rotation.

Answer 2

Given data:

Earth rotates on its axis every 24 hours.

To Find:

How many degrees does a point on the equator travel in one hour? Through how many degrees does a point on the equator travel in one week?

Step-by-step explanation:

Earth completes a full rotation of 360 degrees in 24 hours. So,

The degree of rotation in one hour is,

`=(360 degrees)/(24) =15 degrees`

Hence the degree of rotation in one hour is 15 degrees.

The degree of rotation in one week is,

`=7*24*15degrees=2520degrees`

Hence the degree of rotation in one week is 2520 degrees.

Final Answer:

• The degree of rotation in one hour is 15 degrees.
• The degree of rotation in one week is 2520 degrees.
