Question

How many miles does light travel in 1 hour? The speed of light is `1.86times10^5` miles per second.

Answer 1

The answer is `6.696xx10^8`miles

Explanation:

To compute for this, just simply multiply the speed of light to 1 hour converted to second.

`1 hour xx (60 min)/(1 hour) xx (60 sec)/(1 min) =3600 sec`

Distance traveled = `1.86xx10^5 (mi)/(s) xx 3600s = 6.696xx10^8`miles

Answer 2

`6.696*10^8`

Explanation:

First, we should at least know that there are 60 minutes in an hour and 60 seconds in one minute. Therefore, `60*60=3600` therefore 3600 seconds in an hour. We then multiply 1.86 by 3600 and then we should get something like 6696. We then move three decimals to the left and add 3 to the variable of three to get, `6.696*10^8`.
