Question

a car's speedometer has a percent error of 5% the speedometer currently shows that the car is traveling at a speed of 60 miles per hour which statement describes the actual speed of a car would be

Answer 1

We know that the percent error is 5%, so, if the speed shown by the car is 60 miles per hour, then we have to subtract the percentage error to find the actual speed.

`\begin{gathered} 0.05\cdot60=3 \\ 60-3=57 \\ 60+3=63 \end{gathered}`

The actual speed is 57 miles per hour.

Hence, the right statement is C because the speed could be 57 or 63 miles per hour.
