Speed of sound in air = 340 m/ s

Actual time = (2÷ 2) s= 1 second since after two seconds the girl hears her echo this means that the actual sound took 1s to travel and another 1s to come as echo

Now , we know ,

Speed = distance ÷ time

Therefore , distance= speed × time

=340 × 1

=340m ( ans).
