Miss O’Neill estimated her run distance at 2.8 miles. Her actual distance was 2.4 miles. What was her present error?
To find the present error, you need to subtract the estimated distance from the actual distance:
Present error = Actual distance - Estimated distance
Present error = 2.4 miles - 2.8 miles
Present error = -0.4 miles
Therefore, Miss O’Neill's present error is -0.4 miles.
