<em><u>Solution:</u></em>
Given that, Mrs Franklin's speedometer said she was driving at a rate of 48 miles per hour
When checking the accuracy of her speedometer, an Automotive Specialist recorded her speed at 50 miles per hour
<em><u>The percent error is given by formula:</u></em>
Percent error is the difference between a measured and known value, divided by the known value, multiplied by 100%
From given,
Experimental value = 50
Theoretical value = 48
<em><u>Substituting the values in formula, we get,</u></em>
Thus the percent error is 4.167 %
