Answer: 330×4÷2=660m

Explanation:

The velocity of sound can be calculated by the formula : v=2d÷t. Here,

v is the velocity of sound (here it is 330)

d is the distance travelled by the sound(as the sound is an echo,we should use 2×distance)

t is the time interval between the instance of production of sound and receiving of sound(here it is 4 second)
