The speed of light is approximately 3.0 x 10^8 meters per second. The speed of sound is approximately 3.4 x 10^2 meters per second.

Question

1) What is the difference between the speed of light and the speed of sound?
3.0 x 10^8 - 3.4 x 10^2

2) How many times faster is the speed of light than the speed of sound?
3.0 x 10^8 / 3.4 x 10^2

Answer 1

looks good to me.
You might want to simplify the answers to a single number, though.

Answer 2

So is this correct?

1) 2.9999966 x 10^8

2) what about how many times faster

Answer 3

#1 is correct
#2 is
3.0 x 10^8 / 3.4 x 10^2 = (3.0/3.4) x 10^(8-2)
= 0.882353 x 10^6
= 8.82353 x 10^5
= 882,353 times as fast

Answer 4

2) for this number I could say approximately 900000 faster

Answer 5

yeah, you could.
It depends on what kind of precision you are required to give.
You could also say about a million times ...

Answer 6

Thank you

Answer 7

So what are the answers? sorry its so confusing
