Explanation:

Given : A radar gun measured the speed of a baseball at 103 miles per hour. If the baseball was actually going 102.8 miles per hour.

To find : What was the percent error in this measurement?

Solution :

The actual speed is 103 miles per hour.

The estimated speed is 102.8 miles per hour.

The percentage is given by,

`\text{Percentage}=\frac{\text{Actual-Estimated}}{\text{Actual}}* 100`

`\text{Percentage}=(103-102.8)/(102.8)* 100`

`\text{Percentage}=(0.2)/(102.8)* 100`

`\text{Percentage}=0.194\%`

Therefore, the percent error in this measurement is 0.194%.
