Light travels 186,000 miles in a second. How many feet does it travel in a nanosecond? (A nanosecond is a billionth of a second.) (Round your answer to two decimal places.)
Light travels 186,282 miles per second
1 mile=5,280 feet
186,282 x 5,280 =983,568,960 feet per second-speed of light
1 nanosecond =10^-9 of 1 second
983,568,960 x 10^-9 =0.98 feet in 1 nanosecond=11.8 inches in 1 nanosecond.
