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

The answer is $6.696 \times {10}^{8}$miles

#### Explanation:

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

$1 h o u r \times \frac{60 \min}{1 h o u r} \times \frac{60 \sec}{1 \min} = 3600 \sec$

Distance traveled = $1.86 \times {10}^{5} \frac{m i}{s} \times 3600 s = 6.696 \times {10}^{8}$miles

$6.696 \cdot {10}^{8}$

#### Explanation:

First, we should at least know that there are 60 minutes in an hour and 60 seconds in one minute. Therefore, $60 \cdot 60 = 3600$ 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, $6.696 \cdot {10}^{8}$.
