Answer:
25.96%
Explanation:
Givens
- The old record is 6.75 meters.
- The new record is 8.5 meters.
If 6.75 meters represents 100%, which percentage would represents 8.5 meters? (we use the rule of three).
Then, we subtract 125.96% - 100% = 25.96%
Therefore, the percentage between the two records is 25.96%
