Question

The accepted value of the average distance between Earth and the moon is 384, 467 km. If a scientist measures that the moon is 384,476 km form the Earth, what is the measurement's percentage error?

Answer 1

Percentage error is 0.0024 %

Explanation:

Initial average distance between Earth and moon = 384467 km

Distance measure by the scientist = 384476 km

Total variation in the distance calculation = 384476 – 384467 = 9 km.

Now we can find the percentage by dividing the variation in distance from the initial measurement and then multiply with hundred.

Percentage error = ( 9 / 384467 ) × 100 = 0.0024 %
