An athletes long jump rounded to the nearest metre was 8 m. Whar are the longest and shortest lengths the jump could have been in decimals to the hundredths ?

7.99 meters or 8.01 meters

I don't know

What was the point

To find the longest and shortest possible lengths the jump could have been, let's consider the rounding process.

When the athlete's long jump of 8 meters is rounded to the nearest meter, it means that the actual distance could have been anywhere between 7.5 meters and 8.4 meters.

The longest length occurs when we take the upper limit of the rounding range. So, the longest length would be 8.4 meters.

The shortest length occurs when we take the lower limit of the rounding range. Therefore, the shortest length would be 7.5 meters.

Converting the lengths to decimals to the hundredths:

Longest length: 8.4 meters = 8.40 meters
Shortest length: 7.5 meters = 7.50 meters

Thus, the longest length the jump could have been is 8.40 meters, and the shortest length is 7.50 meters.
