Solution

Step 1: Given
The distance between the two boys = $1020 m$
The time in which the speed of the fire is heard after smoke is seen = $3 s$
We have to find the distance between the two hills.
Step 2: Calculations
The speed of the sound = $D i s \tan c e / t i m e$
= $1020 m$ $/ 3$
= $340 m / s$
Hence, the speed of sound in air is $340 m / s$ .
