Question

Jordan estimated that his paper airplane would fly 42 feet. It actually traveled 50 feet. What was the percent error?

Answer 1

$\huge \mathcal{ Answer࿐}$

• Error (e) = 50 - 42 = 8 feet

• assumed value (a) = 42 feet

$\boxed{ \mathrm{ \% \: error = \dfrac{error}{assumed \: value} \times 100}}$

• $\mathrm{ \% \: error =\dfrac{8}{42}} \times 100$

• $\mathrm{ \% \: error = \dfrac{800}{42} }$

• $\mathrm{ \% \: error = 19.04 \%}$
