Question

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 1

1 mile is 5,280 ft, and 1 second has 1,000,000 microseconds.
So 186,000 miles per second multiplied by 5,280 feet per mile gives 982,080,000 feet per second.
Dividing this value by 1,000,000 microseconds per second gives the final answer of 982.08 feet per microsecond.
