Answer 1

A. Pablo and Eddie both broke the school record this year.

Explanation:

Current record is 12.45seconds

Pablo record is -0.12 seconds which is 12.45 – 0.12 = 12.33 seconds

Eddie’s record is -0.15 seconds which is 12.45 – 0.15 = 12.30 seconds.

Answer 2

Explanation:

the record for the 100 m dash is 12.45 seconds. Since the length of times in the table is relative to the record time, 12.45 seconds,

Pablo's time - 12.45 = -0.12

Pablo's time = -0.12 + 12.45 = 12.33 seconds.

Cindy's time - 12.45 = 0.34

Cindy's time = 0.34 + 12.45 = 12.79 seconds

Eddie's time - 12.45 = -0.15

Eddie's time = -0.15 + 12.45 = 12.3 seconds.

Sam's time - 12.45 = 0.21

Sam's time = 0.21 + 12.45 = 12.66 seconds.

The following statements are true

A. Pablo and Eddie both broke the school record this year.

C. Sam ran the 100-m dash faster than Cindy.

D. Eddie was the fastest runner in the race.
