Question

Vir calculates that an object will take 2.3 seconds to fall to the ground. When Vir times the object falling, it takes 2.5 seconds. What is Vir's percent error ?

Answer 1

His percent error was by .2 of a second, so we can do $\frac{.2}{2.3}$ to get our answer. After dividing, you should have got around .0869. You can convert this to a decimal by moving the decimal spot 2 places to the right to get 8%.
8% is your answer.
