    Speed of sound at STP is different than speed of sound at 20C

    (which is where the answer for wikipedia has 343 m/s)

    Speed of sound at STP (0 C) is 331.4 m/s or 742.03 mi/hr

    after 3 seconds it is 331.4 m/s = 994 .2 meters traveled

    742.03 mph = 1087.3 ft/sec

    in mph 3 * 742.03 mph = 3,262 feet traveled

    Speed of sound at sea level is about 343 m/s if I remember correctly from physics class.

    343 m/s * 3.00 seconds = 1069 meters, or 1070 with sig figs.
