New Worksheet - Science - Speed of Sound

Formulas
frequency = speed of sound / wavelength
speed of sound = (331.5 + 0.60 x temperature of air in Celsius) m/s

Directions
Using the formulas listed above, solve the following problems. Round approximate answers to 2 digits after the decimal.

Problem 1
