If you see a flash of lightnng and it is 3 sec. before you hear the clap, how far away is the storm?

Answer 1

Sound travels approximately 1100 feet/sec. There are 5,280 feet in a mile; therefore, about 1 sec corresponds to 1 mile. Thus 3 sec is about 3 miles. If you want an exact number we can do that too.

Answer 2

can I get an exact number so i can see if I got it.... thanks

Answer 3

Why don't you show your work and let us check it.

Answer 4

ok LOL I am not to good at these formulas...

5280/3 1760m

I have a feeling that is allll wrong

Answer 5

I goofed. The time between seeing the light and hearing the sound is about 5 sec per mile and not 1 sec per mile. therefore 3 sec is a little over 1/2 a mile. But I'll be glad to check your answer. Sound travels at 344 m/s.

Answer 6

would I times 344 m/s with 3 sec? and 1032 m....

Answer 7

Sound travels, at 21 degrees C, about 344 m/s. Therefore, in 3 seconds, the sound would travel 3 sec x 344 m/s = 1032 meters.
1170 ft/sec x 3 sec = 3510 feet. Check me out on that.

Answer 8

yes.
