the error of a measurement with a yard stick is 001 yards W

the error of a measurement with a yard stick is +/- 0.01 yards. What is the maximum probable error in measuring a football field (100 yards)?

Solution

0.01 error in 1 yardstick implies 1% error in measurment.

i.e, 1% error will be accumulated whenever we take measurment.

1% of 100 = 1

Hence Max probable error would be +/- 1 yard while measuring 100 yards.
