If you really want to figure this out you make an equation to solve for the time
let's let
x = time from Elena to Jada and
x = time from Jada to Elena
12 then the equation
12 = 5x +3x
would help figuring out their distance say for one of them
12 = x(5+3)
12/8 = x
1.5 = x
1. 5 hours they will meet up

Answer:
C. 0.0067
Step-by-step explanation:
6.7*10^-3
Write in standard form.
This question pertains to scientific notation, a way to easily express really large or really small numbers.
You'll first notice that 10 has a negative exponent. This tells you that the number is going to be smaller than 10.
This is because 10^-3 translates to 1/10^3 based on exponent rules
With that, you know that your equation is 6.7/10^3
<u>You can simplify that to:</u>
0.0067
In case you didn't know how I got there, 10^3 simply means 10 multiplied by itself 3 times.
The other method would be to look at your answer choices. Since we have a negative exponent, we can eliminate D.
Next, since we have a positive coefficient (6.7), we can eliminate A and B.
That leaves us with the answer C. 0.0067
Option 1, 2, & 4 are irrational numbers
0.88
0.178 is 0.18 or 18% and 0.88 is 88%
just multiply your decimal by 100 to get a percent which is easier to see which is bigger.
