Question

Tyler knows that the distance around a running track is 400 meters. Beth, Tyler’s sister, decides to measure the running track with a meter stick and only gets 392 meters. Her measurement might be off because a track is circular, while a meter stick is straight. What is the percent error of Beth’s measurement

    Answer:

    2%

    Step-by-step explanation:

    True measurements = 400 meters

    Observed measurements = 392 meters

    % error = change in measurements / true measurements × 100/1

    = (400 – 392) / 400 × 100

    = 8/400 × 100

    = 0.02 × 100

    = 2%

    Percentage error of Beth measurements = 2%
