Okay, so in this problem, we are converting the speed of light into, from meters per second, to either kilometers per hour or miles per minute.
00:12
All right, so for part a, we're going to be doing meters to second to kilometers per hour.
00:19
Right, so we start with the unit.
00:21
It gives us, which is 2 .998 times 10 to the 8th.
00:28
That is meters per one second.
00:33
All right, great.
00:35
So i'm just going to go from meters to kilometers pretty easily.
00:39
I can say that 1 ,000 meters is the same thing as 1 kilometer.
00:48
All right, cool.
00:49
So you'll notice that meters are going to cancel there and there.
00:54
All right, like why is going from seconds to hours? i can say that 3 ,600 seconds is the same thing as 1 hour.
01:05
You'll notice seconds cancels there.
01:07
And there...
