Question

The speed of light is 186,000 miles per second, or about 671,000,000 miles per hour. How would
you express these numbers in scientific notation?

Answer 1

Answer:

1.86 10^5 miles/second and 6.71 10^8 miles/hour

Step-by-step explanation:

You would take 186,000 and add a decimal in front of the 1, so it would be 1.86000, and then you want to count the numbers in front of that decimal, since there is five it would be "10^5".

For the second you do the same thing.

1st:

1. 186,000
2. 1.86000
3. 1.86 10^5

2nd:

1. 671,000,000
2. 6.71000000
3. 6.71 10^8
