For this problem, we know that light speed is 1 .86 times 10 to the 5th miles per second.
00:07
Venus is 6 .68 times 10 to the 7th miles for the sun.
00:10
So we're trying to figure out how long it's going to take to light travel to there.
00:14
So what we're going to do here is divide.
00:17
Since we know that it's miles per second and we know that it's going to be 6 .68 times 10 to the 7 miles, we need to figure out what's going to happen per second.
00:28
So for this case here, we're going to divide the 6 .68 times 10 to the 7th.
00:34
That's the amount of miles.
00:35
And we're going to divide it by 1 .86 times 10 to the 5th.
00:40
So what we're using here is that distance is equal to rate times time.
00:45
So to figure out how long it's going to be, we're going to do the distance divided by the rate.
00:50
So we're doing d divided by r is equal to time...
