If you see a flash of lightnng and it is 3 sec. before you hear the clap, how far away is the storm?
Answered by DrBob222
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.

Answered by DrBob222
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.
Answered by Deb
would I times 344 m/s with 3 sec? and 1032 m....
Answered by DrBob222
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.
