Looking at this question, we have the speed of light is 983 ,571 ,072 feet per second.
00:13
For part a, we're looking at what place value is the 5 in.
00:18
Well, we have the ones, tens, hundreds, thousands, ten thousand, hundred thousands.
00:26
So for part a, it is in the hundred thousands column.
00:33
All right, from there, we want to move on to part b.
00:40
And it says, round the speed of light to the nearest 10 million.
00:48
Well, 10 million is going to be right here.
00:53
Okay, so when we look at this nearest 10 million, we see that number is a three.
00:59
The next number is a three, which tells me i'm going to round down.
01:03
So i'm going to keep the eight rounding down, and the rest of my entries are going to be zeros.
01:14
So we have 980 million.
01:20
Sorry, i missed a zero in there...
