Question

Yasmin determines the velocity of a car to be 15m/s. The accepted value for the velocity of the car is 15.6m/s. What is yasmins percent error ?

Answer 1

Percent error is calculated as follows:

% = ( |15-15.6| / 15.6 ) *  100%

% = (0.6/15.6) * 100%

% = 0.0385 * 100%

% = 3.85%

Hope this helped!

Answer 2

For this case we have that the percentage of error is given by the following equation:

$percent\ error= \frac {|v_ {a} -v_ {e}|} {v_ {e}} * 100$

Where:

$v_ {a}:$ Approximate (measured) value: 15

$v_ {e}:$Exact value: 15.6

Substituting:

$percent\ error= \frac {| 15-15.6 |} {15.6} * 100\\percent\ error = \frac {0.6} {15.6} * 100\\% error = 3.85$

Thus, the percentage of error is 3.85%

Answer:

3.85%
