a student ignites a firecracker. The sound is reflected from a wall located at a distance of 275m away and the echo is heard 1.6s after, what is the speed of sound ? so for this, do we double the 275 to get the distance, and then put that and the 1.6s into the equation speed=(distance)/(time) ?
yes, exactly. Use the same procedure as your last question.
thankyouuuu so much ! :D
