Grade 11 Waves and Sound

Exploration geophysicists can determine the depth of an oil well by using the speed of sound in the wave speed equation. Find the depth of the oil well if a rock is dropped into the oil well with an air temperature of 20°C and the sound of its splash into the oil below reaches the geophysicist's ears in 0.77 seconds. How far down is the oil well?
