Light travels at 186,000 miles per second. How many feet does it travel in a microsecond? (A microsecond is a millionth of a second.)

Answer :

Final answer:

Light travels 186,000 miles per second, which is equivalent to 982,080,000 feet per second. Since there are 1,000,000 microseconds in a second, light travels approximately 982.08 feet in a microsecond.

Explanation:

The question asks how far light travels in a microsecond (a millionth of a second). Since light travels at 186,000 miles per second, it's necessary to convert that speed to feet per second by multiplying by 5,280 (the number of feet in a mile). Then we can calculate the distance light travels in a microsecond.

First, convert the speed of light to feet per second:

186,000 miles/second × 5,280 feet/mile = 982,080,000 feet/second

Next, convert one second to microseconds:

1 second = 1,000,000 microseconds

Then divide the speed of light in feet per second by the number of microseconds in a second to find the distance light travels in one microsecond:

982,080,000 feet/second ÷ 1,000,000 microseconds/second = 982.08 feet/microsecond

Therefore, light travels 982.08 feet in a microsecond.
