Clara estimates that the length of a hiking trail is 5.75 km. She later learns that its actual length is 6.25 km. What is the percent error in Clara's estimate, to the nearest tenth of a percent?

Answer:

When you calculate results that are aiming for known values, the percent error formula is useful tool for determining the precision of your calculations. The formula is given by: The experimental value is your calculated value, and the theoretical value is your known value.

% error = | ( experimental – theoretical )/ theoretical| * 100

% error = | ( 5.75 – 6.25)/ 6.25| * 100

% error = 8.0 %
