In an experiment, a student measures the speed of sound in air to be 318 m/s at STP. If the accepted value for the speed of sound under those conditionsis 331 m/s, what is the student's percent error?
a. 3.9% b. 3.93% c. 4.09% d. 4.1%

I tried but it didn't work. This is wat I did:331-318=-13x100=-1300
