Question

sound travels about 11000 feet per second about how many miles away is lightning if 10 seconds pass from the time you see lightning until you hear thunder?

Answer 1

Sound travels 11000 feet EACH second, so in 10 seconds, it travels (10)(11000) = 110000 feet.

To find out how many miles this is, divide by 5280 -- the number of feet in one mile.

110000 divided by 5280 is about 20.8 miles.
