by tiffany duda

find the percent error for the 2nd trial (error =2.8 ft)
0.556881%
0.56%

Explanation:

Step1: Identify the formula for percent error

Percent error = $\frac{\vert error\vert}{actual\ value}\times100\%$

Step2: Substitute the values

Here, error = $2.8$ ft and actual value = $500.0$ ft.
Percent error = $\frac{2.8}{500.0}\times100\%$

Step3: Calculate the value

$\frac{2.8}{500.0}\times100\%=\frac{2.8\times100}{500}\%=\frac{280}{500}\% = 0.56\%$

Answer:

0.56%
