Answer:
In a 1000 days Mercury will make 8.624 more revolutions than Earth!
Step-by-step explanation:
<u>Earth</u> takes 365 days to make a complete revolution.
we can say that the rotational speed of Earth is
so, in a 1000 days how many revolutions will Earth have made?
see that the 'day's cancel out. Simply multiply the two numbers!
<u>Next, do the same for Mercury</u>
we can say that the rotational speed of Mercury is
as it completes 1 revolution in 88 days.
so, in a 1000 days how many revolutions will Mercury have made?
multiplying by 1/88 by 1000 yields:
The Question is how many MORE complete revolutions will Mercury make in 1000 days?
We need to subtract the revolutions of Mercury with Earth to find how far ahead is Mercury from Earth
In a 1000 days Mercury will make 8.624 more revolutions than Earth!
