The length of the basketball court is measured to be 20 metres, correct to the nearest 0.1 metres. Find the range of the actual length of the basketball court.
Solution
Hints:
19.95 m to 20.05 m
The measurement is to the nearest 0.1 m, so the error is \\pm 0.05 \\text{ m}. Range = 20 - 0.05 \\text{ to } 20 + 0.05 = 19.95 \\text{ m to } 20.05 \\text{ m}.
