Group Title
The velocity of sound in air is given by the equation
v = 20√273+t where v is the velocity in meters per second and t is the temperature in degrees Celsius. Find the velocity when the temperature is 117ºC. Round to the nearest meter/sec.

A. 20 meters per second
B. 330 meters per second
C. 395 meters per second
D. 216 meters per second

\(v = 20\sqrt{273+ t}\) since, u want to find the velocity when t = 117, simply replace t with 117 \(v = 20\sqrt{273+ 117}\) = ?

Plug the temperature of 117 into the equation for T and solve.
