(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A bat, flying at a constant speed of 19.5 m/s in a straight line toward a vertical cave wall, makes a single clicking noise and hears the echo 0.15 s later. Assuming that she continued flying at her original speed, how close was she to the wall when she received the echo? Assume a speed of 343 m/s for the speed of sound.

2. Relevant equations

The only equation we were given is speed= change of d/time

3. The attempt at a solution

i took the speed of sound 343*.15s to get 51.45

then i took the speed of the bat 19.5*.15s to get 2.93

then i subtracted the two and got 48.52

this doesn't not seem right any suggestions?

Thank you !
