Question

You measure the width of a doorway and find that it is 0.93 m wide. Find the greatest possible error of your measurement

Answer 1

The right answer is 0.005m

Explanation:

The greatest possible error in a measurement is the half of the measuring unit, it is one hald of the precision unit.

To solve it first you should recognize the measurement unit, in this case meters.

Then, because it is 0.93, you should notice that the last decimal occupies the place of the hundredth, so the GPE might be: 0.01/2 equal to 0.005, your answer.

Answer 2

0.5 m

Explanation:

The greatest possible error is 1/2 of the unit you are measuring in.

We are measuring in meters; this means the greatest possible error is 0.5 m.
