(4) 615 m

Explanation:

From the table we see that the speed of sound in air at 20 °C is 343 m/s. Knowing this we devise the following reasoning:

if the sound travel through the air 343 meters in 1 second

then the sound travel through the air X meters in 2.38 seconds

X = (2.38 × 343) / 1 = 816.35 meters
