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 1

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%
