Question

If it took 1 second for a bat to detect the ultrasound, how far away is the prey?

Answer 1

Answer:

180m! :D

Explanation:

If the speed of sound is 343m/s

The prey is at a distance d than it would take 2d for sound to get back to bat and time is 1s then

Speed=distance/time

340=2d/1

340=2d

180=d

Hope this is right lol
