Air temperature rises linearly from 300 K at the ground to 400 K at 1000 m. The speed of sound at the ground is 347 m/s. Find the time for sound to travel from 1000 m down to the ground. (answer in $s$ ).

Answer:

2.67

Solution:

$t = \frac{2 \times 1000 \times 300}{347 ( 300 + 400 )} = \frac{34641}{347 \times 37.32} = 2.67$ s.
