I measured the distance between two points by the tape measure of the A and B with the scale of 50m.
As a result of having measured by A, it was 833m having measured by B, it was 835m.
When there was the deviation in these two tape measures and compared length of A and B, there was a difference of 12cm by a right measure.
Answer the following questions.
(1) How much is the deviation of A and B with a right measure each ?
(2) It is 1000m of the distance measured in a tape measure of A and how long is the distance in case measured in a right measure ?
(3) How long is the correct distance between two points ?
