Yasmin determines the velocity of a car to be 15 m/s. the accepted value for the velocity of the car is 15.6 m/s. what is yasmin's percent error?

Take the absolute value, meaning positive, of the following equation

(Value found - Value accepted)/(Value accepted)

You will get a 0., then you

0. x 100= percent error

So for your case...

(15-15.6)/15= 0.3846 (absolute value)
0.3846 x 100= 3.846%

If you are doing significant figures it will be 3.8%

Hope this helps!!'
