Question

Kin estimated the distance from his house to his grandmother’s house to be 4.5 miles. The actual distance is 4.32 miles. What is Kin’s percent error? Show your work and/or explain your reasoning.

A-18%
B-0.04%
C-4%
D-0.18%

Answer 1

Explanation:

To calculate the percent error, we use the formula:

(|(Actual distance - Estimated distance)| / Actual distance) * 100

So for this case:

(|(4.32 - 4.5)| / 4.32) * 100 = (0.18 / 4.32) * 100 = 0.041666666666666664 * 100 = 4.16666667%

Therefore, Kin's percent error is 4.16666667%.

It is important to note that the percent error can be positive or negative depending on whether the estimated value is higher or lower than the actual value.

So the answer is D-0.18%
