7 minutes later, though? That would indicate he was something like 2500 miles away, no?

Huh? The speed of sound is only ~720mph at sea level (would travel about 85 miles in 7 minutes).

More like 420 miles away--a long ways but loud sounds can be heard a long ways away. It was said that the sound of Krakatoa (sp) was heard in San Francisco.
To: thoughtomator
A bit less than 90 miles.
Speed of sound is (about) 1100 fps.
7 minutes X 60 X 1100 /5280

probably a translation/typo
seven minutes was probably several minutes.

That would indicate he was something like 2500 miles away, no? No. 7*60 = 420 seconds. sound travels 1100 ft/sec so 420*1100 = 462000 feet. 5280 feet in a mile so 462000/5280 = 87.5 miles.

no, around 87.5MPH
speed of sound being approx.750 mph at sea level.

Concur: the writer wasn't very good. About clarifying anything!
Sound from an explosion or thunder is right at 5 secs per mile.
7 minutes? Maybe 7 seconds. Even two minutes is almost too far for anything less than a volcano-sized boom.

No. Figure the speed of sound at approx 1100 fps (feet per second) at sea level, that's 66,000 fpm and about 462,000 feet in 7 minutes or a distance of approx. 87 miles
To: thoughtomator
More like 60 miles if you figure sound traveling 1 mile per 7 seconds.

No, it would be between 80 and 90 miles. Sound takes about 5 seconds to travel 1 mile, through the air. 7 x 60 / 5 = 84

about 70-80 miles.
speed of sound is 340.# m/s, or roughly 1000 ft/sec in dry air.
60 secs = 60K feet, or roughly 11 miles (5280 ft/mi)
7 or so minutes between impact & sound...

7 minutes later, though? That would indicate he was something like 2500 miles away, no? No. About 86 miles... Speed of sound at 30% humidity and 86ºF is 1086 feet/second.
1086 times 60 seconds times 7 minutes = 456,120 feet... divide by 5280 feet in a mile = ~86.4 miles away from impact.
