For this problem, we will be performing five conversions.
00:04
Or let me say that, again, six conversions.
00:07
I'm just going to get started and set them up, try to talk as little as humanly possible so i can focus on writing.
00:26
You hear something loud.
00:28
My grandson is playing in the basement, some games.
00:35
To convert days to seconds.
00:39
You know that one day has 24 hours.
00:43
We know that one hour has 60 minutes.
00:49
And we know that one minute has 60 seconds.
00:56
Doing the math on this and reporting to three significant figures, i'm going to make a little note that this one needs three significant figures.
01:05
I got 432 ,000 seconds.
01:15
And if you want to report that in scientific notation, there it is.
01:23
Fyi, i usually abbreviate seconds sec because my writing isn't very good.
01:27
And might they look like fives.
01:33
B.
01:34
I'm going to make a note up here that 3 ,600 seconds is one hour.
01:44
And you can see that by looking at 60 times 60.
01:49
For number two, we're going to convert 0 .055 .0 miles, 2 meters.
02:39
Okay.
02:40
So we know there's 5 ,280 feet in a mile.
02:42
There's 12 inches in one foot.
02:44
There's 2 .54 centimeters in an inch.
02:47
There's 100 centimeters in a meter.
02:50
Doing your math on this one, i got 88 .5 meters.
02:57
And that is correct because i checked all my work on an online site.
03:08
C is $1 .89 per gallon.
03:18
We're going to convert that to dollars per liter.
03:23
I only need to convert the denominator...
