Question

The length of a runway is measured as

2500m to the nearest 100m.
What is the minimum possible length of
the runway?

Answer 1

Since the length of the runway is measured to the nearest 100m, the actual length could be anywhere between 2450m and 2549m.

To find the minimum possible length of the runway, we take the lower limit of the range, which is 2450m.

Therefore, the minimum possible length of the runway is 2450m.
