The distance from the Earth to the Sun is 93 million miles. Assume
it takes 365 days for the Earth to travel once around the Sun
the Earth travels in a circle with the Sun at the centre.
(a)
Work out the average speed of the Earth in miles per hour.

roughly 1,000 miles per hour

The earth rotates once every 23 hours, 56 minutes and 4.09053 seconds, called the sidereal period, and its circumference is roughly 40,075 kilometers. Thus, the surface of the earth at the equator moves at a speed of 460 meters per second--or roughly 1,000 miles per hour.

Step-by-step explanation:

is this part of a question or something

answer: 1722

step-by-step explanation:

given: the mass of saturn=

the mass of mercury=

the number of times the mass of saturn is greater than the mass of mercury

hence, the mass of saturn is 1722 times greater than the mass of mercury.
