Question

Light travels one meter in approximately 3.3x10^-9 seconds. How many Kilometers does light travel in one hour? Express your answer in scientific notation.

Answer 1

3.3 * 10^-6 seconds because you add the 3 in the exponent of 1000 to your rate and so 3.3 * 10^-6 is 1000 times slower than 1 meter

Answer 2

so you have that and 3600 seconds per hour.

You equation is like this:

3.3 * 10^-6 m/s * 3600 s/h

The seconds cancel out and you have 3.3 * 10^-6 * 3.6 * 10^3

First we can simplify the powers to get 10^-3

Next we have 3.3 * 3.6 = 11.88 so your answer is this:
1.188 * 10^-3 k/h

Answer 3

Oh ok thank you
