1. The problem statement, all variables and given/known data A student stands 86m from the foot of a cliff, claps her hands, and hears the echo 0.50s later. Calculate speed of sound in air. Known •86m •0.50s 2. Relevant equations V=331.4+0.606T 3. The attempt at a solution V=d/t V=86m/0.50s V=172m/s Is that the first step to the problem? If so I'm not quite sure what the next step is.
