So part a of this question asks us to calculate the earth's average speed as it goes around the sun.
00:07
So speed needs two things in order to be calculated.
00:11
Distance and time.
00:12
We have the distance of the earth's orbit around the sun.
00:15
It's 940 million kilometers.
00:18
We also have the amount of time it takes to do that, which is 365 days.
00:22
However, we have to take this amount of time and change it into hours so we can get our answering kilometers per hour.
00:29
So we take 365 and then we multiply it by 24 because there are 24 hours in a day.
00:35
And we find that in a year there are 8 ,760 hours.
00:39
We then take our two numbers, 940 million for distance and 8 ,760 for time...
