Time = 3 sec
Speed = 1430 m/s
Distance = Speed × Time
= 1430 × 3
= 4290 m
The answer is 4.29 km
I have a doubt since the speed of sound in air is 340 m/s and it is the speed of sound in WATET is 1430 m/s .. But the siren travels through air, right?
ANYWAY, According to the question, the answer, I hope is this.
Just tried to help you out :)
